6.1 PrinCiPleS oF MeASUreMent
By examining the absorbance or transmittance of the sample over a wavelength range we can partially
characterise the sample. Readings of the sample over a range of wavelengths are made and a graph
is plotted of the absorbance or transmittance at each wavelength. As well as observing good practice
(see Good Practice Guidelines) it must be ensured that the sample is stable for the period of the scan
(maximum 70 seconds).
Select the Spectrum Mode from the Main Menu options.
The method screen options will only be displayed if the user logs in. If the user is not logged in the
