A reversed phase gradient ultra performance liquid chromatog. tandem mass spectrometry (UPLC/MS/MS) method has been developed for the anal. of smokeless powders. A total of 20 different components were separated by UPLC and detected by MS/MS in multiple reaction monitoring (MRM) mode. These compounds included diphenylamines, centralites, nitrotoluenes, nitroglycerin, and various phthalates. Simultaneous pos. and neg. electrospray ionization (ESI) was used along with neg. atm. pressure chem. ionization (APCI) to detect all compounds in a single anal. Anal. times were under 8 min with a gradient of 10-73% organic at a flow rate of 0.500 mL/min. With this method, UV and MRM limits of detection ranging from 0.08 to 2.6 ng and 0.4-64 ng injected were achieved. Com. available smokeless powders were also extracted with methylene chloride and characterized using the developed UPLC/MS/MS method. The procedure permits the determination of compositional differences between different brands as well as lot-to-lot variations.
