Application of Nutech Preconcentrator Coupled with GC-MS in the Analysis of Trace Impurities in Fuel Hydrogen Background IntroductionHydrogen fuel cell vehicles are a key application of hydrogen energy. The purity and impurity content of hydrogen fuel have a significant impact on the discharge performance and lifespan of hydrogen fuel cells. Among the impurities that must be

Application of Nutech Canister Sampling & Preconcentration System in Volatile PFAS Monitoring in Stationary Source Emission Abstract PFAS, due to their non-degradability and bio-toxicity, have increasingly garnered attention. While mature and reliable analytical methods exist for detecting PFAS in soil and water, measurement methods for identifying and quantifying volatile PFAS or volatile fluorinated
