Compound Identification
The identity of the 16 peaks in the chromatogram shown was carried
out by comparing the spectra with reference library spectra which
had been previously scanned and stored in the spectral library facility
of the Adept System 4S used.
The spectrum from the reference library which matched the spectrum
of peak 8, is shown and is then superimposed on the scan of peak
8.
Clearly there is a close match and a programmed calculation of
the match, or similarity, gave a match index of 996.5. Very high speed scanning of eluting peaks, “on the fly”, makes purity checks, the determination of optimum monitoring wavelengths for unfamiliar peaks (lambda max scans), and compound identification of peaks using library spectra all possible with considerable cost saving.
