SECTION 5 – MULTIWAVELENGTH / QUANTITATION
The multi wavelength and quantitation measurement mode enables measurements of absorbance, %
transmittance and concentration to be performed. In this measurement mode it is possible to perform
a photometric measurement at up to 20 separate wavelengths. This mode also allows the
concentration of an unknown sample to be determined against a calibration curve or a known
concentration factor at up to three separate wavelengths.
5.1 MENU SCREEN
Select the New Multi Wavelength Measurement
icon on the toolbar. This menu screen
enables multi wavelength measurement
parameters to be changed and standard and
sample information to be entered.
5.2 MULTIWAVELENGTH MEASUREMENT METHOD SET UP
The method tab allows the number of
wavelengths, wavelength values, quantitation
settings and factors to be edited.
5.2.1 Number of Wavelengths
The number of wavelengths can be specified by entering the value into the “Number of WL points” field
or using the Up and Down arrows in this field to adjust the displayed value.
5.2.2 Entering the Measurement Wavelengths
The measurement wavelengths can be specified by entering the values into the available WL 1, WL 2
etc. fields.
