Desorption atmospheric photoionization (DAPPI) is an ambient mass spectrometry (MS) technique that can be used to analyze both polar and nonpolar compounds. Here, the coupling of DAPPI with traveling wave ion mobility-mass spectrometry (TWIM-MS) and application to analysis of food, multivitamin, and pharmaceutical products is described.
