Experience & Innovation

Extensive Experience

with Innovative Titration Sensors

Potentiometry is the method of choice for analytical identication of one or more sub-

stances in mixed phases. Reliable and durable titration sensors from METTLER TOLEDO

with their variety of designs and perfectly matched reference systems, glass membranes

and diaphragms, are suitable for a diversity of applications.

Plug & Play means reliability

With the comprehensive range of Plug

& Play pH, platinum and silver titration sen-

sors, any application challenge can be overcome.

The Sensor Chip in the sensor head stores data such

as sensor type, serial number, calibration data and usable

life, which is automatically read out to the titrator setup when

connected. That ensures, without any action on the part of the opera-

tor, that only the correct sensor with the specic, valid data is used.

Precision and reliability

Alongside experienced craftsmanship, maximum utility

of automated production methods ensures the consis-

tently high quality expected of the sensors.

Enormous capabilities

METTLER TOLEDO has been a source of skills and

expertise for the production of a vast range of titration

sensors capable of meeting the specic analytical re-

quirements of every industry for over 40 years.

Smart design

A clean diaphragm is a fundamental requirement for

precise measurements. It is the interface between the

reference system and the sample. If it is clogged with

precipitation deposits, precise measurement cannot

be guaranteed. The METTLER TOLEDO ARGENTHAL™

Ag/AgCl reference system with silver-ion trap keeps the

reference electrolyte completely free of silver ions, pre-

venting precipitation with sulde, protein or TRIS buffer

containing solutions.

Guaranteed quality

No sensor leaves the production facility untested.

Only on successful completion of the nal check do

the sensors receive their individual quality certicates

ready for dispatch. Strict guidelines regarding the slope

or membrane glass resistance of the pH sensors guar-

antee ultimate performance.

Applications

Application Examples

from Practical Experience

The following small selection of examples shows how the right combination of

METTLER TOLEDO titration sensor and titrator provides the perfect solution for

specic segment applications.

Chemical

Precise sulfuric acid content

using the pH sensor DGi111-SC

The precise determination of sulfuric acid concentra-

tion is of major signicance not only for the chemical

industry but for others too, as small differences can

sometimes have serious consequences for product

characteristics. A titration system consisting of T70

Excellence titrator, Rondo 20 sample changer and

DGi111-SC pH sensor enables automated detection

of 9% sulfuric acid concentration with a deviation of

only 0.01% and an outstanding repeatability of only

0.05% in 6 sample series. Ultimate precision in rou-

tine analysis.

Pharmaceutical

Clotrimazole titration in acetic acid

using the pH sensor DGi113-SC

Important pharmaceuticals such as clotrimazole have

to be titrated directly in non-aqueous solvents due to

their low acidic strength. In accordance with the re-

quirements of the European approved drugs list and

USP, pure acetic acid is used as the solvent and per-

chloric acid as the titrant. The outstanding chemical

stability and ease of regeneration of the DGi113-SC´s

pH glass membrane guarantee the required durability

under such demanding conditions. The high electro-

lyte ow from the moving plastic sleeve is essential for

rapid response and stability of the sensor signal. The

DGi113-SC has all the attributes required for precise re-

sults in non-aqueous titration applications.

Water

Chloride titration in drinking water

using the silver ring sensor DMi141-SC

Chloride in water can occur naturally (e.g. mineral solutions such as brine)

but can also be the result of contamination by fertilizer or waste water.

Among other things, a high chloride content has a destructive effect on

concrete and ferrous metals. With the DMi141-SC, chloride in water can

be titrated with excellent repeatability (relative standard deviation < 0.5%)

over a range of concentrations from 15 ppm to 1% using the appropiate

concentration of silver nitrate titrant.

Beverages

Determining the pH and acidity

of wine using the pH sensor DGi115-SC

The pH and acidity of wine are essential parameters for assessing its

quality. Laboratories have to analyze large numbers of wine samples

for these two variables on a daily basis. A T70 and Rondo 20 sample

changer with the DGi115-SC provide the means for mastering the task as

precisely and efciently as possible.

Electroplating

Automated nickel and hypophosphite titration using

the DP5 Phototrode™ and platinum ring sensor DMi140-SC

Tribological coatings for the automotive industry consist of metal or metal

oxides electroplated or anodized from aqueous solutions. For quality assur-

ance, the baths have to be checked every day. Nickel and hypophosphite/

orthophosphite are titrated in electroless nickel baths using the DP5 and

the DMi140-SC, respectively. The two titrations are handled by two Rondo

20 sample changers that are controlled by a T90 Excellence titrator. At

least 70 samples a day can be analyzed very efciently and reliably.

Generalists and Specialists

for the Chemical Industry

In order to cope with the enormous breadth of analyses from raw materials to special-

ized chemicals, there is not only a need for versatile glass and metal sensors but also

for specialized sensors in order to reliably titrate in a vast diversity of sample matrices.

METTLER TOLEDO can supply the right solutions for these demands.

Chemical

D G i111- S C – the Multi-Talented Acid-Base Titration Sensor

Up to date anywhere, any time

The current data stored in the Sensor Chip such as slope and zero point, monitored sensor

life span, etc. is available to the titrator as soon as it is connected. This information provides

certainty that the DGi111-SC is always in the correct condition required for the application –

regardless of which titrator it is connected.

Mobility means exibility

The movable sleeve holder enables individual positioning of the sensor in the manual titration

vessel or on the Rondo or Rondolino sample changer. That means that smaller sample vol-

umes can be titrated in METTLER TOLEDO standard titration beakers or in Rondo 30 titration

beakers.

Simple yet stable reference

The KCl-ARGENTHAL™ system reliably delivers stable sensor signals within a temperature

range of 0 to 80 °C for the entire life of the sensor. The system is maintenance free and re-

quires only regular lling with 3 M KCl.

Reliable connection to the outside world

A small ceramic pin creates the necessary condi-

tions for slow, even outow of the electrolyte. If

samples with a high sulde or protein content are

avoided, no problems with clogging should be en-

countered.

Quick stable signals and results

The large HA-glass pH membrane has been opti-

mized for rapid response times and stable signals.

It delivers reliably repeatable results in aqueous

systems.

The DGi101-SC and DGi102-Mini

are two powerful micro pH sen-

sors with 3 mm or 6 mm shafts

especially made for small sample

volumes of 5 to 20 mL and for

use on the Rondo 30 or Rondo 60

plus sample changers. With the

moveable sleeve holder, the height

can be adjusted. Samples contain-

ing suldes can be titrated with no

problem. The ARGENTHAL

™ refer-

ence system with silver ion trap

means there is no possibility of

diaphragm clogging.

This is a specic combination for

acid-base titration in media con-

taining hydrouoric acid. The an-

timony pin of the Sb850 half cell

is passivated by uoride ions and

is therefore resistant. Similarly, the

plastic shaft of the DX202-SC refer-

ence is unaffected by hydrouoric

acid. Oxides that are only soluble

in highly corrosive media can be

titrated without any trouble.

Sb850-S7/120 & DX202-SC – where Others Fear to Tread

No mistakes

Because of its Plug & Play Sensor Chip, the DGi116-Solvent is immediately detected as soon

as it is connected to the titrator. Mix-ups are not possible.

Perfectly shielded

The gold shielding on the inner reference provides perfect protection against electrostatic

effects. The signal noise is substantially diminished and the result quality signicantly im-

proved.

Reliable reference system

The LiCl-ARGENTHAL

™ system reliably delivers stable sensor signals within a temperature

range of 0 to 60 °C for the entire life of the sensor. The system is maintenance free and re-

quires only regular lling with 1 mol/L LiCl in ethanol.

Stable signals and easy cleaning

The movable ground glass junction ensures even ow of the electrolyte. The sensor signal

stabilizes faster and titrations can be completed in a shorter time. The smooth glass surface

prevents oil samples from sticking and considerably simplies cleaning.

Fast response times and durability

The large spherical surface area of the glass mem-

brane ensures low membrane resistance and ho-

mogeneous distribution of the potential. So, the

response time and signal noise are reduced. Due

to its chemical stability and easy regeneration, the

A41 membrane glass is ideal for non-aqueous titra-

tions in a pH range of 0 to 12.

Flexibility and Durability

for Difcult Petrochemical Samples

The METTLER TOLEDO sensors for non-aqueous titrations are optimized for rapid response

times and signal stabilization as well as for ruggedness and durability. As a result, they

easily meet the requirements of oil standards such as ASTM, IP and DIN for the titration of

petrochemical products.

The DMi148-SC is ideally suited to

detecting chloride and, by simply

suldizing the silver ring, for titrat-

ing mercaptans in petrochemical

products. Thanks to the pH glass

reference, there is no diaphragm

clogging and no electrolyte relling.

Automatically, other possible appli-

cations such as acid-base titration

using the silver ring as reference

are possible.

With this combination, you have

the option of working strictly ac-

cording to ASTM D664 specica-

tions for determining acid number

or, creating a sensor adapted spe-

cically to the sample and sample

matrix. The DG300-SC half-cell re-

acts quickly and consistently to pH

changes thanks to the large, spher-

ical membrane. The DX200 with its

replaceable bridge electrolyte and

constant electrolyte ow from the

ground glass junction is an indi-

vidually adjustable reference ideally

suited to non-aqueous media.

Controlled Safety and Precision

for Pharmaceuticals

Titrations on the purity of pharmaceutical constituents and active ingredients are funda-

mental to ensuring their effectiveness. METTLER TOLEDO titration sensors make the re-

quired application exibility possible and offer reliability due to their intelligent design.

This ensures maximum sensor life and minimal maintenance.

Pharmaceutical/Biotechnology

DMi147-SC – Twice the Possibilities, Half the Work

Reliable detection:

All relevant sensor data for identication and status monitoring is immediately available to the

titrator thanks to the Plug & Play Sensor Chip.

Secure attachment

With the standard glass sleeve holder, the sensor can be easily and securely positioned

when tted in the titration stand.

Maintenance free reference system

The DMi147-SC has no diaphragm as the pH glass membrane provides a constant reference

potential for the platinum sensor in highly acidic and therefore adequately buffered conditions

required for redox titrations. No relling of electrolyte or cleaning of clogged diaphragms are

necessary, adding up to ease-of-use, minimum maintenance and a long service life.

Twice the capabilities

The DMi147-SC combines two sensors, making it

capable not only of redox titration using the plati-

num sensor but also of acid-base titration using the

pH sensor. In the rst case, the pH membrane is the

reference, in the second the platinum ring. In both

cases, the sample is not contaminated since there

is no outowing electrolyte. The question of the right

choice of reference electrolyte is therefore super-

uous.

Precise Detection

of Multiple Parameters in Water

The importance of water in every area of life and industry is undisputed. The enormous

variety of water types require analysis of different ions and parameters over a wide range

of concentrations under constantly maintained conditions in accordance with strict regula-

tions. That places exacting demands on the sensor systems but presents no problems for

METTLER TOLEDO titration sensors.

Water

DGi117-Water – all Your Water Titration Needs in One Sensor

No watering down of sensor data

The pH sensor calibration data stored in the Sensor Chip of the DGi117-Water are transferred

to the titrator as soon as it is connected. It can be automatically monitored if required, which

means the sensor is always in optimum condition for precise, temperature-adjusted pH mea-

surement and end point titrations.

Maintenance free reference

The double-junction design with a maintenance free internal reference system (KCl gel) en-

ables replacement of the outer reference electrolyte (1 mol/L KCl) and therefore adaptation to

the particular testing conditions.

No interference

The inner tube is electrically shielded by a gold coating, preventing interference from electro-

static charges which otherwise would cause high signal noise and drifting pH readings.

High precision in low-ion media

The electrolyte ow through the xed glass junction remains stable between 5 and 20 µL/h.

This guarantees accurate pH readings and only minimal contamination of the sample with

electrolyte.

All-inclusive

Temperature-adjusted pH readings and end point

titrations can be performed due to the integrated

Pt1000 temperature sensor.

titrations are best left to automated

systems due to the harsh chemical

conditions and high sample num-

bers. The DMi144-SC platinum ring

sensor is capable of fully automat-

ed redox titrations directly in stan-

dard decomposition vessels with

High Precision for Ultimate Functionality

in Electroplating and Electronics

Continuous monitoring of the metal ion, acid or anion content of electrochemical baths

is important for obtaining durable coatings in electroplating processes or producing

perfec tly functioning circuit boards in the electronics industry. Tough and well-designed

METTLER TOLEDO titration sensors are ideal for titrating in such demanding sample

DP5 Phototrode™

Order number: 51109300

inc. region-specic power adaptor (Europe/USA/UK) and cable

DP5 Phototrode™ – a Mini Rainbow for Metal Titrations and More

5 options for a full spectrum of titrations

With a choice of 5 wavelengths comprising 520 nm, 555 nm, 590 nm, 620 nm

and 660 nm, the DP5 can be individually adapted to the specic application. With

a suitable color indicator, a wide range of complexometric titrations is possible,

as well as acid/base, redox and turbidimetric titrations. This means that the cost

benets compared with more complex procedures such as AAS or ICP-AES can be

fully exploited.

Just like a normal sensor

Thanks to its movable sleeve holder, the DP5 can be used like any other sensor in

the titration vessel, either directly on the titrator or on a Rondo or Rondolino sam-

ple changer. It will even t in Rondo 30 titration beakers.

A long-term investment

The polypropylene design of the sensor shaft is resistant against most aqueous

and non-aqueous media. If ever there are incompatible solvent mixtures involved,

you can change to a stainless steel shaft at any time. In either case, you will have

a highly durable sensor which will provide you with reliable readings over the full

length of its extensive service life.

The right solution

The DP5 is used where potentiometric titrations are not possible, where matrix ef-

fects corrupt the output signal of the sensor or where photometry is a specied re-

quirement. It enables quick and easy titration because it requires neither condition-

ing stages nor time-consuming calibration or maintenance work. You just set the

maximum transmission or absorption, and off you go.

Durability

for Paper Production

The process of pulp digestion has to be carefully controlled in order to obtain quality

results without wasting time and money. Due to the vast production volumes, en-

ormous gains can be obtained from very minor changes to the pulping process. The

METTLER TOLEDO sensor DGi114-SC provides the ideal means for titrations in the

delignication process.

Paper & Cellulose / Cosmetics

DGi114-SC – the Tough pH Sensor for Harsh Environments

Unmistakable

Due to its Sensor Chip, the sensor is unmistakably identied. The up-to-date sensor and

calibration data stored are immediately available to the titrator, so mistakes are a thing of

the past.

Stable conditions

The ARGENTHAL

™ reference system with 3 mol/L KCL electrolyte withstands high temperatures

and frequent temperature changes – providing a long-lasting and stable reference system.

Simple maintenance

The movable diaphragm with its high electrolyte ow enables fast and reproducible potential

adjustment and adds to the ease of cleaning and maintenance – all in all an optimum design

for equivalence point titrations with difcult pulp

samples.

Durability for reliable results

The outstanding durability of the HA glass mem-

brane makes it perfect for the demanding condi-

tions of acid-base titrations of black, green or white

liquors.

Surfactants

in a Diversity of Cosmetic Products

Due to constantly rising consumer demands, the composition of personal care products

such as creams, shampoos or shower gels has become increasingly complex. Titrations

of these samples have therefore become extremely exacting, demanding suitable

methods combined with high-performing and versatile sensors: the METTLER TOLEDO

DS800-TwoPhase and DS500 surfactant sensors.

DS800-TwoPhase

The Ultimate in Two-phase

Titration Performance

The DS800-TwoPhase is the sensor

of choice for the titration of anionic

and cationic surfactants in formula-

tions, raw products, liquid deter-

gents and shampoos using the

two-phase titration method accord-

ing to the EN 14480, 14668 and

14669 standards over a pH range

from 1 to 12. The performance ca-

pabilities of the membrane remain

entirely undiminished even after

hundreds of titrations, resulting in

reliable results over the full length

of its extensive service life.

With the sensor DS500, ionic

surfactants can be easily titrated

in aqueous matrices. Very often,

a method based on precipitation

titration between an anionic and

a cationic surfactant is sufcient.

Characteristic titration of that type

can be performed in samples such

as liquid detergent or household

cleaners as well as in colored so-

lutions and turbid suspensions in

a pH range of 2 to 10. Non-ionic

surfactants in raw products can

also be precisely analysed with the

DS500.

Specically for Use

in Aqueous Systems

Excellent Hardware and Firmware

for Optimum Sensor Support

The sensor inputs of the METTLER TOLEDO Excellence T50, T70 and T90 titrators and the

Compact G20 titrator are optimized in terms of speed, signal-to-noise ratio and resolu-

tion. This ensures that in combination with the suitable sensor, stable pH level readings,

pH-stating with tight tolerances or demanding titrations in complex substance mixtures

can be performed to the highest quality standards.

Titration Excellence

Automatic chemical detection

In addition to the Plug & Play sensors the pH buffers used for sensor cali-

bration are also automatically detected by the titrator. It makes no differ-

ence in which order the buffers are measured, saving time and providing

certainty.

Expandable to conductivity

With the unique conductivity sensor card, new application possibilities

such as conductometric titrations or direct measurements can be eas-

ily and reliably done with the full functionality of a modern Excellence

titrator – there is no need for an extra meter. The conductivity card fea-

tures automatic detection of the conductivity sensor and an additional

Plug & Play pH/mV sensor input.

Fully equipped as standard

Every Excellence titrator comes with a versatile pH sensor card. There

are 2 Plug & Play compatible pH/mV sensor inputs, one of which also

features current or voltage polarization, a Pt1000 temperature sensor in-

put and a reference input. This means it has the facility for direct pH or

ISE(pX) measurement, pH end point or pH/mV/pX equivalence point titra-

tions as well as amperometric and voltametric titrations. If needed, more

sensor cards can be added in the available slots.

Ensuring performance capability

In order to ensure the performance capabilities of the sensor inputs, they

can be periodically adjusted with certied resistors and the test unit. The

process is traceable, unambiguously documented, and guarantees identi-

cal measurement conditions for all the sensor inputs of a sensor card. A

calibrated pH sensor can simply be switched from one input to the other

without the need for recalibration.

Efcient method development

The intelligent application modes of the titrators make method optimiza-

tion easy. Just select the titration method and titration speed and the opti-

mum control parameters are automatically set to suit the selected sensor

– simple and efcient method development.

Cables for Plug & Play and Classic Sensors

The METTLER TOLEDO Plug & Play sensors require a Plug & Play cable for connection to the titrators. This cable

can also be used for classical sensors with the exception of the DM143-SC.

Multiple shielding prevents electrostatic effects on the transmission of measurement and reference signals or the

Sensor Chip data.

DM143-SC double platinum pin sensor: for this model, classic sensor cables are used, which can also be

used with all classic sensors. As with the Plug & Play cables, the signal integrity is protected from interference

effects.

Buffer Solutions with Quality Test Certicate

Any pH measurement and end point titration can only be as accurate as the buffer solutions used for calibrat-

ing the pH sensor. The internationally valid pH scale is dened according to the standard reference materials

(SRMs) of the NIST (National Institute of Standards and Technology, USA). The buffer solutions supplied by

METTLER TOLEDO are provided with a quality test certicate that guarantees the stated specications and com-

pliance with the standards. They are ideally suited for use in quality systems.

You can download their test certicates from www.mt.com/buffer and the safety data sheets from

www.mt.com/msds.
