Measured value documentation and quality assurance
Measuring modes
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 con-
stants, addition of constants, addition and subtraction of spectra, for-
mation of the quotient of two spectra
Kinetics
– Absorbance or % transmission mode
– Minimal adjustable scan interval: 1 s (if the absorbance of the test sam-
ple 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
–
Memory for mea-
sured values
Memory capacity
– 5000 single measured values from the
measuring modes, concentration, absor-
bance / % transmission and multi wave-
lengths
– 40 MByte internal memory, sufficient for
approx. 500 spectra and 400 kinetic curves
(sample values based on the following
assumptions: All spectra over a wave-
length range of 600 nm and all kinetic
curves with 150 single values each)
