Each acrylate and methacylate polymer, singly and in mixtures, will produce a unique chromatogram when pyrolyzed. By heating a sample in a dosed system in an inert gas and

SummarySolvent vapors in air may be measured with capillary gas chromatographic columns. By using large diameter columns and sample loops of approximately the same internal diameter, the column may be connected directly to the gas sampling valve. This approach eliminates the use of a splitter or cryogenic trapping and allows low levels to be measured. By operating the column at high velocity, column efficiency is sacrificed for increase in speed.
