Proton-transfer reaction mass spectrometry (PTR-MS) allows for real-time, on-line determination of absolute concentrations of volatile organic compounds (VOCs) with a high sensitivity and low detection limits (in the pptv range). The technique utilizes H₃O⁺ ions for proton-transfer reactions with many common VOCs while having little to no reaction with any constituents commonly present in air. Over the past decades, research has greatly improved the applications and instrumental design of PTR… CONTINUE READING
