Relative intensity plots for 6 ions from the 70 compound mixture with increasing helium content in the transport gas. The separation field was 99.0 Td, 115.5 Td, and 132 Td, for the data present in panes A, B, and C, respectively. The ions were 1) Histamine (m/z 111.6), 2) Leucine (m/z 132), 3) Caffeine (m/z 195), 4) Mephenytoin (m/z 219), 5) Cocaine (m/z 304), and 6) Leucine enkephalin (m/z 556). Increased losses are observed for the majority of ions with increasing helium content in the transport gas. The losses are most dramatic for low m/z ions at high separation voltages. There was a low m/z cut-off when running at the higher 2 separation voltage settings.
