VOC Technologies phone: 1-503-936-6619 (US) www.VOCTEC.com Pneumatic Focusing Gas Chromatography Continuous, web-based, Air Monitoring ----- The GC-in-a-PC VOCTEC patented* Pneumatic Focusing Gas Chromatograph (PFGC=the GC-in-a-PCTM) Pneumatic focusing gas chromatography (PFGC, patented*) is a continuous, specialized monitor for volatile organic compounds (VOCs), Hazardous Air Pollutants (HAPs), ozone precursors, and other air toxics. PFGC compresses an air sample of 1-1000 cc to pressures in the range of 300-1000 psi (20 to 60 atm) before injecting it onto the column of a specialized gas chromatograph, also maintained at high pressure. Pressurization serves to concentrate the sample, thereby increasing sensitivity; remove water vapor by condensation; and allow ease of automation. 30-50 VOCs are routinely measured to 50 parts0-per-trillion sensitivity PFGC is a direct sampling method, which allows for minimal sample loss or interference in the focusing procedure, often not the case in canister and adsorbent sampling systems. Our commercial PFGCs are constructed entirely inside a standard computer case. Furthermore, the GC-in-a-PC is fully web compatible for instrument operation, training, troubleshooting; data display or download; anywhere, through any standard Internet or cell phone connection.

Automatic, programmed multicomponent, internal calibration Dimensions Standard PC Tower Case, 50 lbs Software Advanced application software for peak integration & compound quantification; MS Windows compatible and web-enabled APPLICATIONS Due to its innovation, PFGC has been chosen for ambient air emission monitoring for US superfund sites, ambient air toxics, ozone precursors, public areas (e.g., schools), or specific locations (both outdoor and indoor vapor intrusion) to address possible exposure risk to residents, workers, especially for the most sensitive and vulnerable subpopulations (e.g., elderly, children, schools). Real-time 1-day record of 15 PFGC Chromatograms FEATURES/ BENEFITS • No sample handling, no storage, no adsorbents and no cryogens • Continuous operation with monthly gas cylinder replacement, automatic calibration • High sensitivity & precision; low detection limit, (e.g., 50 ppt for benzene, toluene, PCE, etc.) • On-line software training and trouble shooting • Cost-effective and competitive pricing
