Quantitative Detection of Hexamethylene Triperoxide Diamine in Complex Matrix by Dopant-assisted Photoionization Ion Mobility Spectrometry

Due to the difference in volatility, two-dimensional desorption separation between HMTD and perfume matrix interferents occurred. With the 10th second signal intensity of HMTD in perfume to quantify, the competitive ionization between perfume matrix interferents and HMTD was reduced and the quantitative accuracy improved.
