An indication of the flexibility imparted by computer control of such a spectrometer is given in the
following list of typical facilities for spectra acquisition, display, storage and analysis.
- Display of one or more spectra on a VDU
- Overlay of spectra for comparison
- Spectrum smoothing
- Addition or subtraction of spectra
- Peak search
- Peak identification by reference to a library
- Peak integration
- Storage and recall of spectra on magnetic tape or disks
- Provision of hard copy by x–y plotter or printer
- Energy calibration
- Multiscaling which enables the decay of a nominated region of interest in the spectrum to be
monitored with respect to time. Thus a half-life may be obtained as an aid to isotope identification. - Storage and automatic resetting of instrument parameters
- Correction of data for quantitative analysis
