Stanley K. Yasuda at did a similar analysis at
Los Alamos in a paper entitled "Identification and
characterization of polymers by pyrolytic-hydrogenation gas
chromatography," in J. Chromatogr. 27, no. 1 (1967): 72-84. He
used a modified micropyrolysis unit, a Beroza
microhydrogenation unit containing H2PtCl6.6H2O on Chromosorb W, two
partitioning columns, and a flame ionization detector. A 6 ft.
.times. 0.125 in. outer diam. 30% tricresyl phosphate (I)
and a 30 ft. .times. 0.125 in. outer diam. 25%
hexadecane (II) column were used, each coated on 40/60 mesh
acid-washed C-22 firebrick. Column I was used to screen the
pyrolysis products, and column II was used to separate the
light aliphatic products. By comparing the retention
times of the pyrolysis products with those of an
extensive list of C1-6 aliphatic hydrocarbons
chromatographed on each column, identification of the products
was established. Pyrograms, with chromatographic,
pyrolysis, and hydrogenation conditions, were given for
polystyrene, poly(Me methacrylate) (Lucite), a cyanoacrylate
adhesive (Eastman 910), natural rubber, neoprene, butyl
rubber, butadiene-styrene copolymer, polyisoprene,
polyethylene, and urethane rubber (Estane 5740 X2).
