The results are given in Table 5. APPLICATIONS Cocoa roast gases x] In a study which was aimed at finding a method for abating the odour pollution caused by some cocoa factories, the concentrations of pyrazines, acids, phenols and carbonyl compounds in the emission gases of a number of odour sources of a cocoa factory were measured (Figure 1 ) . Typical chromatograms of the carbonyl compounds and the pyrazines are showns in Figures 4a and 5, while in Figure 6 a chromatogram of a Tenax concentrate is given.
