Ensuring Top-Quality Gases for Gas Chromatography


Since gas chromatography was {{introduced better than a century ago, it’s become an all-important analytical tool in a variety of industries, the pharmaceutical and food industries chief among them. Face it: almost no other techniques for separating and analyzing the components of chemical mixtures are as straightforward, as efficacious, or as exacting. Anymore, gas chromatography is omnipresent in the quantitative and qualitative analysis of complex chemical compositions and the purification of chemical compounds. It’s also generally used to control industrial processes and in the quality-control testing of products.

Of course, the carrier gases necessary for gas chromatography, besides having to be either inert or unreactive, must be at least 99.995% pure – more, in some instances! And that’s where GTW really makes a difference. Now, it’s true, we haven’t existed as long as gas chromatography. But, as a highly regarded PurityPlus® partner producer-distributor, we’ve been supplying chemical researchers and assorted industries with carrier gases of the greatest purity feasible for ages now. We guarantee it, too. Why? Because GTW, like all of the 600 PurityPlus® partner gas production facilities countrywide, is thoroughly inspected and certified yearly by a respected independent third-party organization. Our Western Michigan customers will attest to the purity we deliver.

Which carrier gas we deliver – helium (He), argon (Ar), nitrogen (N2), carbon dioxide (CO2), or hydrogen (H2), predominantly – is subject to the kind of detector in use and the chemical components being researched or tested. Normally, we supply gases appropriate for…

  • Thermal Conductivity Detectors,
  • Flame Ionization Detectors,
  • Electron Capture Detectors,
  • Helium Ionization Detectors,
  • Flame Photometric Detectors,
  • Photo Ionization Detectors,
  • GC-Mass Spectrometry,
  • High-Frequency Discharge Detectors,
  • Discharge Ionization Detectors, and
  • Ultrasonic Detectors

Our Western Michigan customers also depend on us having the carrier gases they need when they need them. Local availability means as well that our customers have speedy access to our technical expertise and can better foster the kind of close relationship with us that’s mutually advantageous.
