• Description:
  Rapid and sensitive detection and analysis of toxic gases is of paramount importance to human health. A field-deployable gas analyzer is highly desirable to help analyze low concentrations of those chemicals in real-time. Through the project, a miniature device called micro-gas chromatography (micro-GC) is developed and constructed. First, all the related components are microfabricated and tested. Second, a highly sensitive detector is developed to detect gas concentrations in the range of parts-per-trillion. Furthermore, the detector's lifetime is significantly extended to make the detector more practical. Finally, a few automated battery-powered micro-GC devices are constructed with an unprecedented size and weight, which can be as low as 0.88 L and 900 g (including the battery box). Gas analysis can be completed in 10 minutes. To further help analyze gas molecules, two algorithms are developed to provide better gas separation ability and gas identification ability. The hardware and algorithms are ready to be translated to industrial companies for further commercialization development. [Description provided by NIOSH]
