Collecting
additional scans
If you choose More Scans when asked whether to add the spectrum to a spectral
window, you can then click the More button near the Collect Status indicator to
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 becomes the Pause button. When all the additional scans have been
collected, the button changes back to the More button.
Collect a sample spectrum
1. Use Experiment Setup in the Collect menu to check the settings of the
experiment parameters.
If the parameters are not set the way you want them, change the settings now
or open an appropriate experiment file. When you are finished setting the
parameters, choose OK.
Note
Warning
You can also select an experiment from the Experiment drop-down list box near the
top of the OMNIC window. ▲
Never stare into the laser beam or at its bright reflection. ▲
2. If Prompt To Insert Or Remove Sample is turned off in the Collect options
(available through Options in the Edit menu) do one of the following:
• If you will be collecting a background first, make sure the system is
ready. (For example, if the application requires that the background be
collected with the beam path clear, remove any sample from the path.)
• If you will not be collecting a background spectrum first, install the
sample.
A background spectrum will be collected first if you have turned on Collect
Background Before Every Sample in the Experiment Setup dialog box.
Skip this step if Prompt To Insert Or Remove Sample is turned on.
