  • GC Detection and Identification by Coupling PID and FID (.pdf)
    A technique has been developed that is based on analyzing the effluent from a gas chromatograph with both photoionization (PID) and flame ionization (FID) detectors. The relative molar response per mole of carbon (RMR) of the FID is similiar for many types of carbon atoms e.g. for aromatic
  • PAS vs. GC for SF6 Monitoring
    Monitor vs. their own Gas Chromatograph w/ an ECD detector. NUCON injected a known quantity of SF6 into their HVAC Test System and pulled bag samples from various points. By knowing the flow rates and SF6 starting concentration, NUCON calculated the expected SF6 values at each point. The samples
  • Air Emissions from the Automobile Manufacturing Industry: A Bio-Oxidation Pilot Study of Paint Emissions Control
    were made to airflow (adjusting residence time) and sump water recirculation spray (biotrickling filter flow rate and biomatrix chamber timing) while monitoring the VOC inlet and outlet concentrations using a gas chromatograph equipped with a flame ionization detector (FID - Method 25A).
  • Ther Versatility of the Vibrating Element (.pdf)
    to the plant’s gas chromatograph (GC) BTU measurement”, is referring to the relationship between specific. gravity and fuel BTU value (Fig 7). The VBE devices are faster and more reliable than the GC but not as accurate. A GC has. a higher accuracy and can speciate a process stream, but at a cost near
