Measuring modes

z Concentration

– Measurement with permanently programmed methods, adapted to the

WTW test set program

– Automatic method selection if test sets with barcodes are used

– Program support for the creation of additional user-defined methods

(max. 100)

– Citation forms and units method dependent

– Display of the absorbance value can be added

– Method data update possible via Internet

z Absorbance / % Transmission

– Measurement against own reference absorbance value possible

z Multi wavelengths

– Freely definable calculations from up to four individual absorbance

values at different wavelengths

– Calculations can be stored as methods (max. 50)

z Spectrum

– Absorbance or % transmission mode

– Limits freely selectable within the wavelength range

– Increment: 1 nm

– Recording duration for the complete wavelength range: < 7 min

– Settings can be stored as profiles (max. 20)

– Evaluation functions: Cursor scanning, zoom, min./max. recognition,

peak area determination, derivation, smoothing, multiplication by
constants, addition of constants, addition and subtraction of spectra,
formation of the quotient of two spectra

z Kinetics

– Absorbance or % transmission mode

– Minimal adjustable scan interval: 1 s (if the absorbance of the test

sample is high, the scan interval is extended due to the longer duration
of the individual measurements)

– Settings can be stored as profiles (max. 20)

– Evaluation functions: Cursor scanning, zoom, min./max. determination,

slope calculation (for an interval or total), enzymatic activity
