Novel mass spectrometric instrument for gaseous and particulate characterization and monitoring
Abstract
Purpose of the instrument is for real-time (less than 1 min), ppB analysis of gaseous/particulate pollutants (VOC's, PAH's, heavy metals, transuranics) from DOE waste cleanup. It will consist of an isokinetic sampler, a pressure transition and sampling region for parallel analyses, two small mass spectrometers (one for organic analysis using field ionization, one 'ion trap' for particulates using pyrolysis and electron-impact ionization), and a personal computer. A dimethylsilicone membrane will be used for the organic vapors. A forward-backward coincidence method will be used in the laser scattering particle detector. The instrument will be easily transportable to DOE waste sites, such as waste storage tanks.
