Single Wavelength Mode

In single wavelength mode, you can monitor a

sample at any wavelength from 190 to 700 nm, at 1

or 2 sensitivities. Plus, you can direct one output

channel to trace the percent of UV or visible light

transmitted through the sample.

Following is a description of the parameters on the

display for single wavelength mode. The absorbance

at the currently selected wavelength appears in the

upper left of the display. You use the display to set

the new wavelength, sensitivities for output

channels 1 and 2, and peak width.

Description

In the first line of the display, specify the desired

monitor wavelength. The default is 254 nm, and

the valid range is 190 to 700 nm.

Note: If the lamp saver option is enabled and you

indicate a wavelength not in the range of the

currently lit lamp, the detector lights the necessary

lamp. (For the UV lamp, the process of lighting the

lamp takes about 30 seconds.) Allow the baseline

to stabilize before using the new wavelength.

for information on the lamp saver

option. By default, the lamp saver option is enabled.
