6.6Wavelength Scan mode – recording of absorbance and transmittance spectrums

In the wavelength scan mode, the absorbance of the light in a solution over a defined wavelength spectrum is measured.

The measurement results can be displayed as a curve, as percent transmittance (%T) or as absorbance (Abs). The collected data can be printed as a table or a curve.

The data are available for formatting changes. These include automatic scaling and zoom functions. Maximum and minimum values are determined and shown as a table.

The cursor can be moved to any point on the curve for the purpose of reading off the absorbance or transmittance value and the wavelength. The data associated with each data point can also be shown as a table.

		From the displayed list of stored scans, a record is selected for use as a reference
		scan/superimposed scan. This can be highlighted or shown in the background in comparison
	Reference Off/On	with the actual measured scan.
		Note: This option is only available when there are stored scans with the same wavelength range
		and step.
