Off-line pyrolysis techniques

Typical GC analysis can be performed after the desorption of the SPME fiber in the injection port of a GC instrument [22]. 

Besides derivatization or selective analysis using SPME, off-line pyrolysis before a chromatographic analysis can be used for various other purposes. One such purpose is the use in the pyrolyzer of larger samples, which would not be appropriate to send directly into a GC instrument. Larger sample must be used in specific applications, for example in the analysis of trace components in pyrolysates. Another application of offline systems Is found when a dedicated GC or GC-MS instrument cannot be afforded only for pyrolysate analysis.
