Figure 5 The Use of the GC/MS System to Determine the Nature of a Complex Envelope of Three peaks from the Separation of Rosewood Oil on a Conventional Packed Column

 

The MS scans over the envelope containing four unresolved peaks (peaks 1,2 3 and 4 shown in figure 4) allow the mass spectra of each component to be extracted for structure elucidation as shown in figure 5. These results were all obtained in the late 1950s and firmly established the principle of coupling separation and identification techniques in a single instrumental entity for the separation and identification of complex mixtures of volatile substances.
