Developments in pyrolysis capillary GC

Gas chromatography

“…The extensive use of pyrolysis gas chromatography in polymer characterization is illustrated by a book (10) and recent reviews (20,30). Current activities were discussed by Liebman (40), and developments in WCOT column pyrolysis GC have been reviewed (50). WCOT pyrolysis applications are increasing with improvements in methodology.…”

Sample Preparation for Chromatographic Analysis

“…The primary pyrolysis products are quenched as they rapidly expand away into the cooler regions, diminishing the possibility of forming secondary products. Because of the large swept volume of the pyrolyzer and the fact that the pyrolysis products are produced over a finite time, the direct coupling of the pyrolyzer to open tubular column gas chromatography raises some additional problems [846,[854][855][856]. The reproducibility of individual pyrograms depends on the sample size and homogeneity, the temperature profile of the pyrolyzer, and the maintenance of uniform conditions for transferring the pyrolyzates to the column [841,842,846,852].…”

Rubber

“…Instrumentation used in PY-GC was described (110,111). Applications of PY-GC-MS for some new polymers were shown and the pyrolysis products identified (112).…”

“…Quantitative and qualitative analysis of polymers and additives by chromatographic and spectroscopic techniques was reviewed (17) with respect to the advantages of automation and computerization. Other reviews covered the fields of SEC (18), dynamic properties and compound performance (19), analytical trends in elastomer characterization (20), polymer characterization (21), degradation and pyrolysis mechanisms (22), pyrolysis and GC in polymer analysis (23), microstructure of synthetic polymers (24), and computer applications in polymer laboratory (25).…”
