Development of a novel ion source for μ-plasma induced proton transfer reaction mass spectrometry

摘要

Instrumentation: 1. New ion source design compatible with an ABSciex API 3200 MS. 2. Stacked reaction chamber system allows the separation of primary plasma, reagent ion generation and analyte protonation: (1) No significant "backflush" of N_2 into the reagent chamber was observed. 3. The required kinetic control was verified up to approx. 1 ppmV total analyte mixing ratio.
