Portable Methane Measurement in Marine Engine Exhaust With Nutech 3000 Portable FID Analyzer Background Marine engine exhaust is hot, wet and particle-laden, and methane levels can change quickly with engine load. During a two-week field evaluation, the Nutech 3000 operated beside an established methane analyzer to test whether a portable system could provide stable,

Trace Analysis of 10 Volatile Sulfur Compounds in Air Using Canister Sampling and Nutech 8910 Preconcentrator with GC–FPD Overview Volatile sulfur compounds are important target pollutants in ambient air and fugitive emissions. Their accurate determination can be technically challenging because compounds such as hydrogen sulfide and thiols are chemically reactive and susceptible to adsorption,
