I run unstabilized liquid hydrocarbon on a GC but I want to quantify the C9+ into groups e.g C9= 12% mass, C10= 15% mass etc which the GC cant do. So I need to do a second analysis on DHA to determine the individual group % of the C9+ region but I can only do this on stabilized hydrocarbon liquid. So do I apply the alkane group % (C9, C10, C11, C12, C13 etc) from the stabilized DHA analysis to the unstabilized C9+ on the other GC
