Pausing
and continuing
data collection
The Pause button in the Collect Background window lets you pause data
collection before all the scans have been collected. After you pause the collection,
you can add the spectrum to a spectral window using the window selection box.
When you choose Pause, the button changes to the Continue button. To continue
data collection where it left off, choose Continue. The button will change back to
the Pause button.
Collecting additional
background scans
When data collection is finished, the Pause button changes to the More button.
The More button lets you collect additional scans. They will be averaged with the
data collected so far, thereby improving the signal-to-noise ratio. When you
choose More, a dialog box lets you enter the number of additional scans you want
to collect.
After you enter a number and choose OK, data collection resumes and the More
button changes to the Pause button. When all the additional scans have been
collected, the button changes back to the More button.
Collect a background spectrum
1. Remove any sample from the sample compartment or sampling
accessory.
Warning
Never stare into the laser beam or at its bright reflection. ▲
2. Use Experiment Setup in the Collect menu to check the experiment
parameters.
If the parameters are not set the way you want them, change the settings now
or open an appropriate experiment file. If you are using a sampling accessory,
set the parameters so that the background is measured through the accessory.
When you are finished setting the parameters, choose OK.
Note
You can also select an experiment from the Experiment drop-down list box near
the top of the OMNIC window. ▲
3. Choose Collect Background from the Collect menu.
The Collect Background window appears. Follow the instructions that appear
on the screen.
