Output Channels

The following table lists what data are transmitted
via each output channel.
Channel 1: detection at wavelength 1 (sensitivity 1)
Channel 2: detection at wavelength 2 (sensitivity 2)
Channel 3: ratio of wavelength signals

Example Run

You can use your HPLC system to separate a mixture
of polynuclear aromatic hydrocarbons (PAH). You'll
monitor the column effluent at two wavelengths
240 nm and 287 nm, because each reveals strong
absorbance by PAH. Since the absorbance is high at
both wavelengths, you monitor at relatively low
sensitivity (0.2) to detect large peaks.
Start detector
If necessary, start the detector as described on page
3-12.
Choose Mode
If the following display is not shown, press Mode at
the first display of the current mode, and then
press Dual.
