Three distinct chromatographic techniques for coal tar pitch volatiles (CTPV) are presented: (1) an LC method for calculating total polycyclic aromatic hydrocarbons (3- to 6-ring); (2) a capillary GC method for identifying and quantifying interference by mineral oil; and (3) a column chromatographic technique for separating PAH from oil on a class basis. A discussion of an unknown fraction commonly found in CTPV samples, but which cannot be measured by traditional chromatographic techniques, is also given. Conclusions are drawn for specific aluminium plant data on the composition of CTPV samples.
