3-66 Using the Detector
Getting information about a stored spectrum
To get information about a stored spectrum
1. Select SCAN (Shift, Chart Mark).
2. Press 3 Get scan info.
A slot number box appears, its default, Last (for the most recently stored
spectrum).
3. Press Enter for information about the last stored spectrum.
As an alternative, press the number (1 to 5) of the stored spectrum about
which you want information, and then press Enter. A screen containing
the following information appears:
• Storage slot number – Of the selected scan (or “Last scan”)
• Scan type – Displays the chosen type of scan performed
• λ range – Displays the wavelength range for the selected spectrum
• λ other – The wavelength setting of the stationary monochromator
• Pace – Displays the pace for the selected spectrum
• Gain – The gain setting for the PMT (it can sometimes be necessary
to increase the gain value when working with for low sample
concentrations)
4. Press Enter to return to the scan list.
Reviewing a stored spectrum
To review a stored spectrum:
1. Select SCAN (Shift, Chart Mark).
2. Press 4 Review.
Tip: Selecting Review retrieves both the zero-scan and sample scan.
3. Specify the storage slot number (1 through 5) of the spectrum you want
to review, and then press Enter.
Tip: “Retrieving spectrum n” appears, and then the stored spectrum
appears. You can view the stored spectrum graphically, and adjust the
wavelength and EU ranges, if necessary. You can also run a new sample
scan based on the retrieved zero-scan.
