Liquid chromatographic method has been developed for the determination of 1,4-diamino-2,3-dihydroanthraquinone DDA, 2-21-quinolinyl- 1,3-indandione QID, 1-methylamino-anthraquinone MAA, and 1,4-di-p- toluidinoanthraquinone DTA. A relatively rapid and reliable HPLC method has been developed for the determination of selected colored smokes on glass fiber filter discs. The sample preparation process was streamlined by extracting the colored-smokesdisc samples into acetonitrile followed by filtration and direct injection into a high performance liquid chromatograph equipped with a programmable ultraviolet UV spectrophotometric detector. A mixed-mode C18 cation column provided adequate resolution and optimal peak symmetry for all four of the colored smokes investigated. The precision and accuracy data and detection limits are included in the report.
