Abstract

See full text

Devices and techniques for ion analysis, including ion mobility separation and mass spectrometry, are provided using a dual polarity spark ion source and having the flexibility required to optimize the detection performance for a broad range of illicit substances with different physical and chemical properties. In various embodiments, the volatility and electro-chemical aspects may be addressed by the system described herein by performing real-time detection of compounds detectable in both positive and negative polarities and/or prioritizing spectra acquisition in a given polarity due to the high volatility and therefore short residence of certain target compounds.
