Collected vapour condensates represented 16 vol% (BGVC) or 17 vol%
(G/MTBE) of the initial liquids (BG or BG+MTBE respectively). Analysis
of equilibrium vapour in headspace above BG+MTBE heated to 130F/54C in
20 ml vials indicated an MTBE vapour content of 19.3% (GC-FID, Chevron
SE-30 analysis): using this as a target, MTBE vapour content of 21.3
vol% was measured during the large-scale generation of G+MTBE vapour for
test article (G/MTBE vapour condensate) collection, using a slightly
different GC-FID method under GLP.
