Gas chroinatographic

analysis of hydrogen peroxide solutions*

The usual methods for analysis of H,O, solutions are time consuming and require samples of at least 0.1 ml, the more highly concentrated samples requiring weighing because of bubble formation. They are further burdened with interference by organic materialsr. We report here a rapid ( N IO min) method applicable to samples in the ,ul range which requires no precise knowledge of the sample size. We have found no inherent limitations to the accuracy and precision of our method other than the normal limitations of gas chromatographic techniques in general.

Sometimes it is desirable to analyze for H,O, along with organic materials (e.g. products from combustion reactions). We tested our method on mixtures of H,O,, HzO, CH30H and CH,O to get an idea of its applicability to these systems.

The principle of the method is the quantitative catalytic decomposition of H,O, into H,O and, 0, on hot platinum gauze with quantitative analysis of these two products on a gcas chromatographic column.
