Figure 4. The Separation of Rosewood Oil.

The use of the MS12 GC system for the analysis of rose wood oil is shown in figures 4 and 5. The separation shown in figure 4 is an excellent example of the early packed columns which had limited efficiency and thus the mass spectrometer was used to compensate for the limited resolution

It was this type of application for GC/MS in the 1950s and 1960s that provided a tremendous impetus for research by the essential oil industry. Over the intervening years, this work has resulted in the synthesis and production of many unique flavor and perfume compounds. The advantage of the GC/MS combination is demonstrated in figure 5.
