Abstract
A system and method for analyzing volatile organic compounds (VOCs) adsorbed on an adsorbent membrane, by low-temperature plasma and mass spectrometry (LTP-MS). The system includes a receptacle for receiving the adsorbent membrane, a low-temperature plasma ionizer configured to emit a plasma stream in a plasma emission direction, thereby ionizing the VOCs adsorbed by the membrane and forming a VOC-laden ionized gas, and a mass spectrometer for analyzing the ionized VOCs.
Claims17
A system for analyzing volatile organic compounds (VOCs) that have been collected by contact sampling on an adsorbent interface membrane, by low-temperature plasma and mass spectrometry (LTP-MS), comprising:
- an adsorbent interface membrane permeable to VOCs, having a first face and a second face, said adsorbent interface membrane configured to ensure controlled diffusion of the VOCs from the first face to the second face:
- a receptacle for receiving the adsorbent interface membrane, the receptacle positioning the adsorbent interface membrane such that the first face is contactable with a VOC source for sampling;
- a low-temperature plasma ionizer configured to emit a plasma stream in a plasma emission direction, ionizing the VOCs adsorbed by the adsorbent interface membrane to diffuse the VOCs to the second face of the adsorbent interface membrane to form an ionized gas laden with VOCs;
- and
- a mass spectrometer configured to analyze the ionized gas laden with VOCs.
