Factors Affecting the Reproducibility in Pyrolysis Gas Chromatography (PGC)
The achievement of interlaboratory reproducibility in PGC, similar to that of IR, MS and NMR, will open new possibilities for analysis and greatly expand PGC’s utility. Normalized pyrograms obtained under standard conditions could be compiled and used as reference spectra. The accumulation of compiled reference data will permit the deduction of modes of thermal fragmentation which, in turn, could be used for interpretation of new pyrograms not listed in the compiled data. To bring about the realization of this potential, the PGC subgroup of the British GC Discussion Group has undertaken a detailed study into the problems of interlaboratory reproducibility in PGC (1). It should be emphasized that excellent qualitative and quantitative intralaboratory reproducibility has been achieved by many workers (2) and therefore should not be confused with problems of interlaboratory reproducibility.
