Soldin and colleagues argue that atmospheric pressure chemical ionization (APCI
) is suboptimal for steroid analysis and should be superseded by the use of atmospheric pressure photoionization (APPI).
This study was conducted to develop a method of detection and analysis of TC using LCMS comparing the performance of ESI, APCI
In order to introduce gas sample directly into the ionization region, APCI
source of Xevo[TM] TQ MS (Waters, USA) was modified and the schematic diagram was shown in Figure 1.
