GOW-MAC® Instrument Co. refurbishes or provides replacement thermal conductivity detectors (TCDs) for Bruker, formerly Varian Chromatography, gas chromatographs (GCs), at substantial cost savings.

Each detector meets original equipment specifications and comes ready to install in your legacy Varian GC. Rebuilding includes thoroughly dismantling, cleaning internal channels and tubing, installing new filaments, leak checking, and testing to ensure noise and drift meet original specifications. 

The detector is made of stainless steel and comes with rhenium-tungsten (WX) filaments as standard. Special filaments for reactive samples are available upon request. Corrosion resistant detectors utilising nickel, Monel®, titanium or gold-plated thermal conductivity blocks are also offered. 

In addition to Bruker, GOW-MAC provides replacement TCDs for other major brand gas chromatographs on the market today, including many older instruments.

GOW-MAC is a leading manufacturer of gas analysis instrumentation and long known for their expertise in, and manufacturing of, thermal conductivity detectors.
