摘要: Due to the growing need monitor aircraft cabin, cockpit and breathing-line air quality, functional assessment of sampling equipment for specialised field conditions flight be established both in-flight ground safety. In this article, we assess reliability Tenax TA thermal desorption tubes perform under various relevant conditions, such as storage temperature, loading vibrational velocity, gravitational force (G Force) altitude pressure with semi-real-time gas chromatograph-mass spectrometer (GC-MS) analysis on portable HAPSITE® ER (Hazardous Air Pollutants Site Extended Range) instrument. First, show that can handle extreme environmental 4–77°C, over numerous analytical test cycles. Next, confirm hot (77°C) cold (4°C), does not affect tubes. Then, illustrate ...
