Favorites List of methods/tests created by the user to suit his own requirements.
Single Wavelength
Single wavelength readings are:
Absorbance readings: The light absorbed by the sample is measured in absorbance units.
Transmittance reading (%): Measures the percent of the original light that passes through the
sample and reaches the detector.
Concentration readings: A concentration factor can be entered to enable the measured
absorbance values to be converted into concentration values.
Multi Wavelength In the Multi Wavelength mode, absorbance (Abs) or percentage transmittance (%T) is
measured at up to four wavelengths and absorbance differences and absorbance relationships
are calculated. Simple conversions into concentrations can also be carried out.
Wavelength Scan
A wavelength scan shows how the light from a sample is absorbed over a defined wavelength
spectrum. This function can be used to determine the wavelength at which the maximum
absorbance value can be measured. The absorbance behavior is displayed graphically during
the scan.
Time course The time scan records the absorbance or % transmittance at a wavelength over a defined
time.

5.4.10 Standard Addition - monitoring/checking results
The accuracy of readings (their correspondence with the actual
concentration of the analyte in the sample) and their precision
(correspondence of the reading results obtained from several
samples containing the same concentration of the test analyte)
can be determined or improved using the standard addition
method
This method (also known as standard-addition or spiking) serves
to detect sample-specific faults:
•The analysis was compromised by substances or
interferences in the sample (sample matrix effect),
•defective measuring device,
•impure reagents.
Method:
Add a defined quantity (concentration) of the substance to be
tested to the sample as a standard solution. The detection rate
(concentration of the added standard solution) should be close to
100%.
Detection rate = Reading of successful standard addition
Expanded value after successful standard addition
Detection rate Conclusion
100% Probability that the reading results are correct
is high.
100%
Assumption: The analysis was compromised
by substances or interferences in the sample
(sample matrix effect)
Test to determine whether a sample matrix
effect is present:
Use distilled water instead of the sample. Add
standard solution as described in the
procedure.
Detection rate Conclusion

5.5 Barcode Programs
A special barcode reader in cell compartment #1 automatically
reads the barcode on the 13 mm cuvette/vial as the cuvette/vial
completes a single rotation. The instrument uses the barcode
identification to automatically set the correct wavelength for the
analysis and calculates the result immediately with the help of
stored factors.
In addition, readings are recorded at 10 different positions during
a rotation. A special outlier-elimination program is run and then
the average of the measured values is calculated. Cell and round
cell faults and contaminations are detected and therefore a very
precise result is determined.
5.5.1 Perform a barcode test
1. Prepare the barcode test in accordance with the work
instruction and insert the cell into the cell compartment (1).
•When a coded cell is inserted into the cell compartment
(1) (Figure 3, Page 21), the corresponding measurement
program is automatically activated in the main menu.
•Otherwise select in the main menu the menu option
Barcode Programs and insert a zero cell (depending on
work instruction) into the cell compartment (1).
Note: To obtain further information on the Help Guide ("Information"
symbol), refer to Appendix A, Page 149.
The measurement is started automatically and the results are
shown.
Note: To define a sample dilution, press the Dilution key in the toolbar.
To evaluate other cell tests and other parameters insert the
prepared cell into the cell compartment and read off the result.
Note: The control bar, which is shown on the right on the display, shows
the relationship of the measurement result with the measurement range.
The blue bar shows the reading result independently of any dilution
factor that was entered.

Dilution Factor Off/On
A corrective dilution factor can be entered in order to take account of certain properties.
The number entered at the dilution factor prompt will be multiplied by the result to compensate
for the adjustment. For example, if the sample has been diluted by a factor of 2, enter 2. The
default setting of the dilution factor is turned off.
Note: During use of a dilution factor, the dilution symbol is shown on the display.
Note: If undiluted samples are used, set the dilution factor off.
Chemical Form Some of the stored tests/methods allow to select the chemical form and the measuring range.
Reagent Blank: Off/On
The function "Reagent Blank" is available for several barcode tests. This enables the reagent
blank value to be added to or subtracted from, the subsequent readings. The reagent blank
value shifts the calibration curve along the y-axis, without changing the shape or gradient of the
curve. The effect corresponds to a y-axis intercept of the calibration straight line. This is clarified
by the following formula: concentration =[conc. factor) * Abs] - (reagent blank)

5.5.4 Sample blank
Turbidity and colour in the sample matrix can falsify the results of
a photometric analysis. The interference factors come from the
sample or are created by reactions with the reagents.
The influence of turbidity and/or colour can be eliminated or
reduced by taking a sample blank reading.
After the sample reading has been carried out, a special cell
(LCW919) with the sample blank is inserted in the cell
compartment. Measurement is automatic. The value of the
sample measurement is then corrected through addition or
subtraction of the blank value. The end result is shown in the
display with the blank value correction icon.
With some tests the determination of a sample blank value is not
necessary, as during the test procedure turbidities and coloring
are already recorded.

The measurement process defines the handling and the readings
of the test:
•At which and how many wavelengths should readings be
completed?
•How many absorbance readings must be completed?
•When should the zero reading and the sample reading be
completed?
•Are waiting times necessary between readings?

readings)
The Single Wavelength mode can be used in three ways. For
sample readings at a single wavelength, the instrument can be
programmed to measure the absorbance, % transmittance or
concentration of the analyte.
•Absorbance readings: The light absorbed by the sample is
measured in absorbance units.
•% Transmittance measures the percent of the original light
that passes through the sample and reaches the detector.
•Turning on the concentration factor allows selection of a
specific multiplier for converting absorbance readings to
concentration. In a graph of concentration versus the
absorbance, the concentration factor is the slope of the line.

1 cm rectangular cells available.
Additional information can be found in the carousel user manual.
6.8.7 LINK2sc
Link2SC enables the exchange of measurement values between
online process probes and the DR 6000. This enables online data
to be verified and process probes to be corrected as necessary.
The online data is sent to the DR 6000 in a "job file". After the
laboratory measurement values have been produced, the job file
is sent to the controller again for the corresponding probe to be
corrected.
Data transfer is either via memory card or network (LAN). Please
take a precise description from the LINK2sc user manual
(DOC012.xx.90329).
6.8.8 DR 6000 website
Use this function to call up a website via an existing network
connection. Current software updates, as well as documentation
and information on the DR 6000 can be found here.
