RFID technology on turntables
What’s RFID means and how does it work?
Radio Frequency IDentification (RFID) is a generic term that is used to
describe a system that transmits the identity (in the form of a unique
serial number) of an object or person wirelessly, using radio waves. It's
grouped under the broad category of automatic identification
technologies.
It’s the combination of a “tag” and a “reader”. A typical RFID tag consists
of a microchip attached to a radio antenna mounted on a substrate. The
chip can store data. The reader is used to retrieve the data stored on an
RFID tag. A typical reader is a device that has one or more antennas that
emit radio waves and receive signals back from the tag. The reader then
passes the information in digital form to a computer system.
In our assembly an RFID tag is attached inside the turntable at the first
beaker level position. This tag is clearly visible.

Presentation
RFID reader mounted inside the Magnetic stirrer assembly
SAC850 on the left and SAC950 on the right
The RFID reader is mounted inside the Magnetic stirrer assembly (see
figure above). When an analysis is started and a turntable is in place, the
sample changer rotates the tray (and the arm in the case of a SAC950)
so that the tag and the reader are face to face for a moment.
Which data contains a turntable RFID tag?
The turntable identification data (type of turntable, number of beakers,
beaker location and beaker size/height).
Benefits of using RFID technology on turntables
The Sample Changer knows at any moment if a turntable is installed and
which turntable is used.
Possibility of working with magnetic bars without risks of interferences.

Running sequence with a workstation
After having started a sequence from the workstation or TitraMaster 85,
the sample changer performs the following operations if 1 to 9 dynamic
rinses and if 2 static rinses R1 and R2 have been programmed (*):
1.
Moves to Park beaker (**) and starts rinsing dynamically the
electrodes. At the end, the Park beaker is left empty.
See paragraph "Dynamic rinsing".
2.
Moves to R1 beaker (***), dips the electrodes into that beaker and
rinses under stirring during a preset delay. See paragraph "Stirring".
3.
Moves to R2 beaker (***), dips the electrodes into that beaker and
rinses under stirring during a preset delay. See paragraph "Stirring".
4.
Moves to beaker no.1, prepares sample/standard running the
sample preparation number attached to the method. During this
time, the workstation displays the message "Sample changer
processing in beaker 1" message.
See paragraph "Sample preparation".
5.
At the end of analysis, starts rinsing dynamically the electrodes. At
the end, the beaker no.1 is left nearly empty with a small amount of
solvent that was used to flush the electrodes and delivery tips.
(*)
The number of static rinses (0, 1 (R1) or 2 (R1 and R2)), the duration of
static rinses and the number of dynamic rinses (0 to 9) are programmed
in the Setup > Configuration parameters of the workstation (refer to the
Reference Manual of the workstation used).
(**)
A dynamic rinse before first beaker analysis can occur in the Park or in
the R1 beaker if 0 or 1 static rinse has been programmed. Selection
between Park and R1 is made in the Setup > Configuration parameters
of the workstation (refer to the Reference Manual of the workstation
used).

Dynamic rinsing
1 to 9 Dynamic rinses (or shower rinse/emptying operations) can be
performed between 2 sample runs. A Dynamic rinse is carried out in the
just analysed sample beaker or in the Park beaker (*). At the start of a
sequence, the dynamic rinse can be performed either in the Park beaker or
in R2 (static rinse no.2) beaker (*). Dynamic rinses never take place in
calibration beakers. At the end of a calibration beaker analysis, the
dynamic rinse is performed in the Park or R2 (static rinse no.2) beaker (*).
A Dynamic rinse consists of the following operations:
1.
The electrode are positioned above the rinse beaker.
2.
The electrodes move down in the beaker. The beaker is emptied to a
waste in the same time. At the end, the electrodes are located in the
emptied beaker at their downmost position.
3.
The electrodes move up slowly. In the same time, the electrodes are
washed with rinse solution (usually demineralised water) and the
resulting solution is emptied very slowly to a waste. At the end, the
electrodes are located above a beaker filled with rinse solution and
some remaining impurities.
4.
The electrodes move down in the beaker. The beaker is emptied to a
waste in the same time. At the end, the electrodes are located in the
emptied beaker at their downmost position. Then, a last rinsing of the
electrodes and delivery tips is carried out.
5.
The electrodes move up. At the end, the electrodes are located above
a nearly emptied beaker containing a little solvent that was used to
flush the electrodes and delivery tips.
Steps 3 and 4 can be repeated up to 8 times as up to 9 dynamic rinses can
be programmed. Steps 2 to 4 are performed under stirring.
(*)

Depending on the selection made in the Setup > Configuration
parameters of the workstation (refer to the Reference Manual of the
workstation used).
Use
Stirring
A magnetic and a propeller stirrer can be used to stir the solutions. When
the propeller stirrer is connected (see chapter "Setting up"), it will be
automatically used in place of the built-in magnetic stirrer. The stirrer
speed is set in the Cell menu of the workstation (value adjustable
between 100 and 1100 rpm by steps of 50 rpm).
Dynamic and static rinses are performed under stirring.
Magnetic stirring with a SAC950
When using a 2 or 3-radii turntable with a SAC950, you must use a
propeller stirrer to stir the solutions that are placed on the smallest row (2radii turntable) or on the 2 smallest rows (3-radii turntable).
Green positions : magnetic and propeller stirring possible
Red positions : propeller stirring only

Sample preparation
A SAC850 or SAC950 can run up to 10 different sample preparations in a
sequence. Sample preparations are created and edited from
TitraMaster 85 PC PC software.
Each element of a sample changer sequence is associated to a sample
preparation. A sample preparation is a succession of up to 10 elementary
actions required by the sample changer to prepare each sample beakers
to be run thereafter.
On running a sequence, the workstation sends to the sample changer all
sample preparations to be runned for the sequence. The compatibility
between the sample preparation and the sample changer used is tested
and an error message is displayed in case of failure (example: use of a
peristaltic pump that is not installed yet).
See TitraMaster 85 on line help, topics "Handling sample preparations".
Important:
When starting a sample preparation, if you have a solid or powder sample
in the beaker or if you have, for some beakers, less liquid than a
minimum height limit (see chapter "Accessories - Beakers"), then you
must disable the "beaker presence detection" option before running the
sequence. If you keep that option activated, then the sample changer will
not prepare the sample in that beaker and will jump to the next beaker
considering that the current position is empty.
To disable the "beaker presence detection" option in TitraMaster 85 , see
TitraMaster 85 on line help, topics "Editing an application - Configuration".
Actions that can be done during a sample preparation:
Control peristaltic pump.
Start/stop electrode rinsing.
Start/stop beaker emptying.
Control stirring.
Set delay.
Control stirrer.
TTL command (wait for a TTL IN for a preset time).
44
Use
5. T
Trroubleshooting
A number of tests are automatically performed when the sample changer
is switched on and during calibration and sample batch measurements.
The errors reported can be divided in two groups:
•
Autotest errors occuring on switching on the sample changer and
errors occuring while operating the sample changer alone (manual
mode without workstation).
•
Errors displayed by the workstation.
Autotest and manual mode errors
If an error is detected, the sample changer stops the current action and
the status lamp turns to red.
Switch off the sample changer, identify the causes of the error (generally,
arm or turntable blocked or arm or turntable movement obstructed),
correct the error then switch on the instrument.

ARM or TURNTABLE
OBSTRUCTED
The arm or turntable has been blocked and
cannot function properly. Remove the
obstruction and press Resume analysis
(key 1) to continue the sequence from the
point it stopped.
On starting a sequence,the sample changer
cannot read the RFID tag of the turntable.
Check that a turntable is correctly mounted
on the sample changer. Check the model of
turntable used. See chapter "Accessories".
Restart the sequence.
A rinse beaker is missing or has not been
positioned properly on the sample changer.
Either position a beaker or terminate the
operation and enter the correct number of
rinses.
If you want to continue with the next beaker
in the analysis, press 1 Resume analysis.
Either the data transmission between
sample changer and the workstation cannot
be performed properly, in which case you
should check the cable connections, or the
measurement stopped due to a movement
error. Terminate the cycle by pressing key
Stop on the SAC950 sample changer
keypad or key Stop of the workstation, and
check that nothing is obstructing sample
changer's movements.

SAMPLE PREPARATION
IMPOSSIBLE
The sample changer cannot run the sample
preparation the workstation is asking for.
Example:
A reagent addition is programmed in the
sample preparation and no peristaltic
pump is installed on the sample changer.
RINSE PROCEDURE
IMPOSSIBLE
Review the Edit method parameters,
parameter Sample preparation no and/or
install missing pumps
For TitraMaster 85 users only, check and,
if necessary, edit the sample preparation
routine.
The sample changer cannot run the rinse

Example:
You have programmed 2 static rinses and a
first dymamic rinse in the second static
rinse beaker (R2 beaker). Only 1 beaker is
available for static rinses (beaker R1) if you
intend to rinse dynamically the electrodes in
a static rinse beaker.
