the massive data matrix is possible and provides excellent results (36), no
software, which is compatible with all of the various GC
GC analyses, is yet

An overview of the state-of-the-art of GC
GC is given in (43).

14.5 RESIDUE-CONTAINING PRODUCTS

These products comprise whole crude oils, as well as bottom fractions of distilling
units and (partly) converted materials. The common property of these products is the
fact that they contain high-boiling material which is not amenable to gas chromato-
graphic analysis.
