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.

Perform a barcode test

1. Prepare the barcode test in accordance with the work instruction

and insert the cell into the cell compartment (1).

Single Wavelength (absorbance, concentration and

transmittance 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.
