High resolution separation column Pyrolysis

Ishida and co-workers [14] applied reactive pyrolysis of copolymer polyacetals in the presence of cobalt sulfate incorporated into Py-GC equipped with a high-resolution capillary separation column. The method was successfully applied to study the sequence distributions in polyacetals containing low levels of copolymerised ethylene oxide units. The E contents and the distributions of E sequences up to E in polymers were evaluated on the basis of peak intensities of cyclic ethers containing E units on the pyrogram. 

A significant step in the evolution of analytical pyrolysis was the combination of pyrolysis with a sophisticated physiochemical technique for the efficient separation and/or identification of the fragments. In 1959, a combined Py/GC system of polymers was introduced. Improvements in the analysis conditions were obtained by using the high-resolution capabilities of capillary columns. In 1970, a continued interest in the analysis of extraterrestrial samples such as lunar rocks and the Allende me-terorite (found in Mexico) was reported, using the modified Py/GC/MS technique. Applying a pyrolysis/mass...
