摘要：

A custom set of ion volumes was manufactured in order to investigate the gain and byproducts using hydrogen as a buffer gas following electron ionization in a quadrupole ion trap mass spectrometer as compared with helium. Analyses of illicit drugs such as cocaine, codeine, and oxycodone, and explosives such as TNT, RDX, and HMTD with ion volume exit orifices of 1 mm, 2 mm, 4 mm, 6 mm, 8 mm and 10 mm were performed using GC/MS. Strong similarities between hydrogen and helium spectra of illicit drugs and explosives provide evidence that hydrogen can be used effectively as a buffer gas in an ion trap mass spectrometer.
