8.6 NIST Library Searches
The laptop will come pre-loaded with identification software from the National
Institute of Standards and Technology’s (NIST) Mass Spectral Search Program,
which contains approximately 192,000 spectra. This library compares the sample
spectra to the library spectra in order to determine the SI number based upon purity
and fit, the ratio of the intensities of the unknown spectra to the library spectra.
1 Refer to section 8.3, Accessing the Data Review Feature, on page 8-2 to open
a data file.
2 Double-click on the peak of interest. The green scan cursor will relocate to the
peak. Use the arrow keys on the laptop to adjust the scan cursor. The optimal
location of the scan cursor is at the apex of the peak. (See Figure 8-49.)
