Sampling tralns conslstlng of glass flber and silver membrane filters and wpport pad ageernblleo followed by different commercially available sorbent tubes were evaluated for the simultaneous determination of alrborne quinollne, Indole, 2amlnoblphenyl, and carbazole by means of a speclaiiy constructed vapor generation apparatus. Tenax was the sorbent of choke slnce relatlvely poor and inconsktent recoverles were obtalned wlth silica gel and XAO-2 had a poor load capaclty for the amines. For 500-L alr samples collected at 17-22 *C and 45-60% relative humMlty over 4 h, the load capaclty of the 100 mg Tenax front sectlon was ca. 70 pg (140 pg/m3) and the capacity of the whole sampling train exceeded 160 pg (320 pg/m3) If equal amounts of the four amines were present.
