Kinetics
The Kinetics function allows the temporal tracing of the absorbance and
transmission of a sample with a particular wavelength.
The photometer automatically calculates the slope between two adjacent
measuring points from the available measurement data.
If necessary, the catalytic activity can also be determined and displayed.
To record the kinetics, the photometer carries out single measurements at
regular time intervals (measurement intervals) and saves the measurement
values as a function of the time.
All settings for a recording are administrated as a profile. Profiles can be cre-
ated, stored, edited and deleted. Each measurement assumes an appropri-
ate profile.
4.9.1
Creating/editing profiles for Kinetics recordings
A profile for a Kinetics recording includes the following details:
Profiles for Kinetics recordings are saved under the numbers
4001 to 4020.
In the delivery condition, a profile is stored for demonstration pur-
poses.
