Smart Chemistry researches and develops analytical methods for hydrogen fuel at detection limits 10 to 1000 times lower than those required by SAE J2719 and ISO 14687.
From the fueling nozzle to the lab to the certification report.
Custom-designed equipment for sampling particulate and gaseous hydrogen at 700 bar and 350 bar high-flow fueling nozzles — meeting SAE J2719 and ISO 14687 requirements.
Analytical methods for sulfur compounds, inorganic gases, particulates, and organics — detection limits 10 to 1000× lower than required by industry standards.
Evaluation and certification of the accuracy of hydrogen gas-measuring devices at California hydrogen stations.
Written under contracts with the National Renewable Energy Lab (NREL) and California Fuel Cell Partnership (CaFCP). An eighth method is currently in development.

Dr. Hsu has spent his career building the analytical foundation of the modern hydrogen economy. Under contracts with the National Renewable Energy Lab (NREL) and California Fuel Cell Partnership (CaFCP), he authored seven ASTM standard methods for hydrogen fuel sampling and analysis.
Smart Chemistry has analyzed or sampled hydrogen fuel from every one of the 100+ hydrogen fueling stations in the USA, Canada, and Europe — under SAE J2719 and ISO 14687.
Smart Chemistry also provides evaluation and certification service for the accuracy of hydrogen gas-measuring devices at California hydrogen stations.
