AN-09 – Measurement of sulfur-based compounds in hydrogen with enhanced plasma discharge (Epd) technology

A sample containing sulfur-based compounds in hydrogen was analyzed using gas chromatography with the enhanced plasma discharge (Epd) technology. Results show detection of all sulfur-based compounds with a LOD down to 1ppb. The method’s sensitivity was further increased with sample pre-concentration using ASDevices’ PLSV valve and its unique peak remodeling algorithm (patent pending). Epd technology is a revolutionary alternative to sulfur chemiluminescence detectors (SCD) and flame photometric detectors (FPD) for the measurement of sulfur-based impurities in fuel-grade hydrogen.
