Application of a two-stage scheme of gas chromatographic analysis of unstable reforming catalysate

Petroleum

“…Since the number of possible isomers makes the identification of individual components highly impractical in higher boiling petroleum fractions, even with the separating power of gas chromatography, more attention has been given to the quick analysis of hydrocarbon types in these fractions. Dorokhov et al (441) described a system for the two-stage GC analysis of unstable catalytic reformate. The instrument consisted of two chromatographs connected in series by means of a six-way stopcock.…”
