Overview
An all in one unit for measuring trace impurities(ppb/ppm) N2-Ar-HeO2-CH4-CO-CO2- NMHC-sulfurs-formaldehyde-ammonia-halogenated-formic acid and water in hydrogen. The unit is capable of meeting the ultra-high purity requirements for hydrogen used in fuel cells as set out in ISO 14687.
The HyDetek system uses a combination of LDetek’s plasma emission detector, thermal conductivity detector and a quartz crystal moisture sensor to measure all critical impurities. It is suitable for use in electrolysis systems producing green hydrogen as well as steam methane reforming processes and grey hydrogen.
