A method is described which makes possible a direct determination of nitrocellulose in double‐base powder and powder paste after separation from low‐molecular components by gel permeation chromatography and subsequent integration of the nitrocellulose peak. It is also possible to determine nitroglycerin and stabilizers in the same sample by collecting the components in the low‐molecular peak and subsequent injection into a reversed‐phase chromatography system. The procedure is exemplified on a powder paste containing nitrocellulose, nitroglycerin, centralite I, and diethylphthalate. The whole quantitation procedure will take less than an hour.
