PORTABLE GAS CHROMATOGRAPHY MASS SPECTROMETER WITH A RAPID HEATING CARBON NANOTUBE PASTE

摘要

Recently, a miniaturized ion trap mass spectrometer with cold electron ionization was developed by our group as an ultra-portable mass spectrometer [1]. To extend the applicable field of the portable MS to a complex gas mixture analysis, we integrated a gas chromatography (GC) system to the miniaturized ion trap mass spectrometer using a nano-liter valve interface and evaluated the analytical performances of the system using typical volatile organic compounds.
