The 15, W1, W2, and 3 condensateswere also similar to each other (Figs. 21, 22); however, the two groupswere quite dissimilar in that the non-condensables from the latter fourashes contained major components that were present in much lower quantitiesor did not appear in the former group.

See Figure 19 for identification of the numbered peaks.The condensable fraction from the yrolysis of the W1 sampleby GC-MS. The major components detected were the n-paraffins with 13 to 28carbon atoms per molecule. The compounds present in the largest quantitieswere n-Clj, n-Cl8. n-C2 and n-Cz8 (Fig. 23). In a studydiscussed in EPRI (1-C2z9 and n-C27-31 were thedominant hydrocarbons iin the 575 to 816 ug/kgconcentration range.
