Determination of Water in Pyrotechnic Mixtures by Gas Chromatography
Abstract
A procedure, using gas chromatography, has been developed for the analysis of water in pyrotechnic mixtures. Regression analysis of data indicated that with benzene as internal standard, weight of water could be determined to within plus or minus 0.001 gram in the examined range of 0.001 to 0.022 grams of water. Water was extracted from the pyrotechnic mix with absolute methanol. An internal standard (benzene or n-pentane) was added to the resultant slurry. After solids had settled, a sample of the clear liquid for resolution and analysis was injected into a gas chromatograph fitted with a Porapak Q filled column. Standard solutions, prepared with the same ratio of internal standard to methanol extract of pyrotechnic mix and various amounts of water, were resolved under similar conditions on the chromatograph. A calibration curve was prepared.
