An instrument is being developed that will be capable of providing real-time (<1 minute), quantitative, chemical analysis of gaseous and particulate pollutants generated from DOE waste cleanup activities. The instrument can detect and identify volatile organic compounds, polynuclear aromatic hydrocarbons, heavy metals, and transuranic species released during waste cleanup. It consists of an isokinetic sampler operable up to 500 K and wide flow rate range, a high- to low-pressure transition and sampling region separating particles from vapors for separate analysis, two small mass spectrometers (one for organic analysis by field ionization and one for particulate analysis by thermal pyrolysis and electron-impact ionization), and a powerful PC for control/data acquisition. Initially, the instrument will used with the K-1435 Toxic Substances Control Act (TSCA) incinerator at K-25; other applications are also possible, eg, vitrification monitoring, storage tank offgassing analysis, etc. It will be easily transportable.
