4.9 Kinetics
The Kinetics function enables the temporal tracing of the absorbance or
transmission of a sample at a certain wavelength.
The photometer automatically calculates the slope between two adjacent
measuring points from the available measurement data.
The catalytic activity can also be determined and displayed if required.
To record the kinetics, the photometer carries out single measurements at
regular intervals (measuring interval) and stores the measured values as a
time function.
All settings for a recording are administrated as a profile. Profiles can be cre-
ated, stored, edited and deleted. Each measurement requires a respective
profile.
4.9.1 Creating/editing profiles for Kinetics recordings
Note
Profiles for Kinetics records are stored under the numbers 4001 to 4020.
In the delivery condition, a profile is stored for demonstration purposes.
A profile for a Kinetics recording comprises the following data:
Input field Possible entries
Number * 4001 ... 4020
Name Any name (max. 18 characters)
Mode* Absorbance or Transmission
Wavelength* Freely selectable (in nm)
Duration* Total duration in the format hh:mm:ss
(hours:minutes:seconds)
Interval* Measuring interval = time interval between two
successive single measurements in the format
hh:mm:ss (hours:minutes:seconds)
Exception:
With the setting, Measurements/interval: Max/
interval the interval is defined differently (see
below).
Delay Time between the start of the recording and the
start of the first single measurement
Scaling Auto or Manual
