Our instruments trace their roots back to the mid 1930s — back to an automotive engine analyzer utilizing a thermal conductivity detector, or TCD. This first product, in turn, led to the development of a variety of TCDs and binary gas analyzers, such as those for the analysis of air in H2 and the comparison of natural vs. manufactured gas.

Today, our line of gas analysis solutions is extensive. Depending on the targeted application, GOW-MAC gas chromatographs and gas analyzers may use TCD, PID (PhotoIonization Detection), FID (Flame Ionization Detection), FPD (Flame Photometric Detection), HFADD (High Frequency Argon Discharge Detector), colorimetric, or electro-optical detection to provide solutions for a wide range of applications. We continue to partner with the compressed gas industry in working to address the requirements of quality assurance while also working to maintain overall laboratory throughput. All of our instruments are fully engineered systems that are industry proven, rugged workhorses, and easy to use. Our skilled team of engineers works very closely with you to ensure that the gas analysis instrument or system we design for you will be the most efficient solution for your specific application.

Our on-line and laboratory analytical products include:

  • Gas Chromatographs
  • Gas Analyzers (trace, binary, toxic)
  • Total and Aromatic Hydrocarbon Analyzers
  • Gas Leak Detectors
  • Custom process/on-line analyzer Packaged Labs

We also provide GC / gas analyzer detectors for OEMs (Discharge Ionization (DID), Thermal Conductivity (TCD), and Flame Ionization (FID), as well as Repair / replacement.
