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
