The determination of the binary system samples which are difficult to analyze in ordinary gas chromatography was carried out by photolysis-gas chromatography, using the vapor phase photolysis in the presence of small amounts of H
2S as a radical scavenger.
The five binary system samples shown in Table 1 were chosen as typical examples.
Super high pressure mercury arc was used as a light source, and the photolysis products were analyzed by gas chromatograph in the same manner as reported before.
In each system, the plot of the molar ratio of the two components against the molar ratio of the photolytic products (2, 3, 5 in Table 1), or the plot of the partial pressure of a component against the amounts of products (1, 4 in Table 1) gave straight lines.
No mutual interferences of the components were found in the photolysis reaction.
