“For close to 30 years, I have used GOW-MAC GC’s for the measurement of ppm levels of impurities in gaseous helium. All of the analyzers have been extremely accurate and reliable.The few times that I have required technical help, the assistance has been timely and helpful. I highly recommend GOW-MAC analyzers for this application.”

“GOW-MAC is the first company I think of any and all of my specialty gas analysis or detection needs!”

"It has been my experience that Gow-Mac maintains the availability of their repair parts much longer than most GC manufacturers. This is a huge benefit to organizations that have a very limited budget for equipment replacement."
