Development of a drift tube mass spectrometer associated with plasma microjets

Résumé

The objective of our instrument is the detection of Volatile Organic Compounds (VOCs) at trace level either in air or deposited on surfaces. The mass analyzer is a drift tube associated with a linear quadrupole and we are designing a linear ion trap for a more compact version. We will use Plasmas microjets in order to desorb molecules of low volatility deposited on surfaces. In the first version of our instrument precursor ions are formed in a glow discharge, then react with the air at a pressure of about 1 mbar in the drift tube and are then mass analyzed with a quadrupole mass filter. Compounds of low volatility are deposited on surfaces. In order to desorb them we will use plasmas microjets operated with Ar.
