Using Hydrogen as An Alternative Carrier Gas for US EPA 8260
Using Hydrogen as An Alternative Carrier Gas for US EPA 8260
7 Sept 2015Due to regional shortages and increasing costs of helium, the preferred carrier gas in gas chromatography, alternative carrier gas options are increasing in demand. The application note evaluates the Teledyne Tekmar Atomx VOC Sample Prep System in conjunction with a Thermo Scientific TRACE 1310 / ISQ GCMS while employing hydrogen GC carrier gas and nitrogen purge gas to perform EPA method 8260C. A working linear calibration curve, Method Detection Limits (MDLs), and a BFB tuning evaluation will be presented to determine the validity of alternative helium gases for VOC analysis by USEPA 8260C.

GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Volatile Organic Compounds (VOCs)Volatile organic compounds (VOCs) are chemicals that have a low boiling point. Some VOCs are harmful to human health, whereas others can be used to determine the shelf-life of foods samples. Carrier Gas
