Placing collected spectra<br />

into new spectral windows<br />

If you want collected spectra to be placed into a new spectral window<br />

automatically after each data collection, turn on Collect To A New Window. The<br />

new window will be given a default title.<br />

If you turn this option off, you will be asked whether to place the collected<br />

spectrum into a spectral window. See “Collecting a sample spectrum” and<br />

“Collecting a background spectrum” in the “Collect” chapter for details.<br />

Note<br />

If this option is on, you will not be able to view information about data collection<br />

problems at the end of the collection. ▲<br />

Displaying prompts to<br />

insert and remove the sample<br />

Prompt To Insert Or Remove Sample lets you specify whether the software will<br />

prompt you to install or remove your sample at the appropriate time during data<br />

collection. The actual prompts that appear depend on the current setting of<br />

Background Handling in the Experiment Setup dialog box.<br />

For example, if you are collecting a background spectrum before every sample<br />

spectrum and Prompt To Insert Or Remove Sample has been turned on, you will<br />

be prompted to prepare the system for background collection at the start of data<br />

collection. If you are collecting a background after every sample, you will be<br />

prompted to install your sample at the start of data collection. The same prompt<br />

will appear if you have set the software to collect a background after a specified<br />

time or if you are using a stored background. See “Background Handling” in the<br />

“Collect” chapter for more information on background handling.<br />

If you don’t want to be prompted, turn off Prompt To Insert Or Remove Sample.<br />

In this case, make sure the system is ready for background collection (if you are<br />

collecting a background first) or the sample is installed (if you are using any of the<br />

other Background Handling settings) before choosing Collect Sample from the<br />

Collect menu. See “Collecting a sample spectrum” in the “Collect” chapter for<br />

complete information on collecting sample spectra.<br />
