          • Food & Beverage (Flavor & Aroma) – Most of what is perceived as flavors in foods are actually the aromas and odors that are being detected by our sense of smell. The human nose is far more sensitive to most flavor and odor compounds than are GCMS systems, so proper detection, identification and quantitation of these compounds requires sample enrichment.

      • Industrial & Manufacturing Applications

          • Siloxanes & Biogas (Landfill Digesters) – Volatile siloxanes can cause considerable damage to power generation equipment through the build-up of silicon dioxide created from combustion at burners. Siloxanes coat turbine blades and heat exchangers degrading performance and eventually causing failure.
          • Material Emissions & Product Safety – Chemical emissions from plastics, textiles, carpets, building materials, and any other natural or synthetic products all combine to add volatile chemicals to the air in indoor environments.
          • Electronic Manufg/Clean Rooms – Due to their size (.2~3.0 nm), AMCs can pass through ulta-low particulate air filters. AMC’s are of great concern to any sensitive micro-electronics manufacturing process, especially in nano-technology applications.

        • Chemical Weapons Detection – Exhaled breath not only contains high concentrations of carbon dioxide and water vapor, but also contains a signature of all chemicals in the blood that have at least some vapor pressure to allow their exchange from the blood into the exhaled breath through the alveoli in the lungs.
        • Weapons Source Investigation – Exhaled breath not only contains high concentrations of carbon dioxide and water vapor, but also contains a signature of all chemicals in the blood that have at least some vapor pressure to allow their exchange from the blood into the exhaled breath through the alveoli in the lungs.

          • Arson & Crime Investigation – MiniCansTM and Bottle-VacsTM allow accelerant extraction from debris the same day, rather than waiting 24 hours required for classical charcoal strip passive transfer and solvent extraction, with 10 to 100 times greater sensitivity!
          • Drug Lab Detection – MiniCansTM and Bottle-VacsTM allow accelerant extraction from debris the same day, rather than waiting 24 hours required for classical charcoal strip passive transfer and solvent extraction, with 10 to 100 times greater sensitivity!
          • Detection of Drugs of Abuse in Breath – MiniCansTM and Bottle-VacsTM allow accelerant extraction from debris the same day, rather than waiting 24 hours required for classical charcoal strip passive transfer and solvent extraction, with 10 to 100 times greater sensitivity!

              • Disease Biomarkers in Breath (Metabolomic VOCs) – Exhaled breath not only contains high concentrations of carbon dioxide and water vapor, but also contains a signature of all chemicals in the blood that have at least some vapor pressure to allow their exchange from the blood into the exhaled breath through the alveoli in the lungs.
              • Disease Biomarkers in Blood, Saliva, Urine (Metabolomic VOCs) – VASE’s unique approach for extracting low volatility chemicals for direct injection into a GCMS is opening new possibilities into the detection of specific disease-related volatile and semi-volatile markers.
