Description
1
Absorbance or %T (transmission) at a single user defined wavelength.
2
Colorimetric assay at a single wavelength based on a simple Factor entered or calculated from a
single standard.
3
Spectral plot between two user defined wavelengths. Range 200-950 nm, with user configurable
peak finding function.
4
Kinetic colorimetric assay either rate or end value based.
5
Colorimetric assay at a single wavelength based on a user programmed curve.
6
Absorbance or %T (transmission) at up to 5 user defined wavelengths.
7
Ratio of absorbance values at two user specified wavelengths.
Menu/Options
Within each function the user has the possibility to select various options that define the way results are treated. If not
using a stored method, it is advisable to check that these options have been appropriately set for your experiment
when coming to the instrument. Note that setting the “History” parameter to On (see Preferences later) will cause the
instrument to store its last settings. If the “History” parameter is turned Off, all parameters and selections will return to
their default settings when leaving that application. (Unless it has been saved as a method).
