Air separation

Summary

 

    SDL offers a wide range of gas chromatographs (GC) for air separation applications (ASU etc.). Our analyzers are typically used to control the production, storage and loading of the gases.

    Our gas chromatographs (GC) are typically used for purified feed air analysis, product gas analysis, trace impurity analysis, N2 and O2 analysis in Ar gas, various O2 analysis, total hydrocarbon impurity analysis, trace Nanalysis, etc.
