Re: Probably GC actually ... D86 ?
D86 - to determine the boiling range, not to look at the distillate fractions. We use D86 data as a useful characteristic of petroleum distillates. Once heavier than kero and in the gasoil range, the information in GC is really too much data - when the IBP, 5%,50%,95% and FBP will tell you a lot about the source. It will aslo give some indication of flash point, if you have not got a flash point apparatus available.
I would not use IR though - most light petroleum fractions would look too similar.
