Gas sensors and analyzers can be externally calibrated with standard gases. These gas cylinders are usually difficult to obtain when it comes to low concentration standards, and their lifetime may be questionable. Starting from high concentration and diluting on site to desired lower concentrations allows to set up multi-point calibrations of the analytical device, such as an electronic nose. Volatile Organic Compounds (VOCs), including odorous chemicals, have been analyzed using Gas Chromatography (GC) often coupled with Mass Spectrometry (GC-MS), or specific olfactometric sensors. Proton Transfer Reaction (PTR) coupled with Fourier Transorm Ion Cyclotron Resonance (FTICR) MS is proposed to analyse low level of VOCs in air. FTICR MS is the most accurate and has the highest mass resolution of the MS techniques. B-Trap is a miniaturized FTICR instrument meant for real time VOCs analysis [1–4]. [ABSTRACT FROM AUTHOR] |
