Assuring Superior-Quality Gases for Gas Chromatography


Ever since gas chromatography was {{introduced better than a century ago, it’s become a requisite analytical tool in various industries, the pharmaceutical and food industries foremost among them. Face it: few other ways of separating and analyzing the components of chemical mixtures are as straightforward, as effective, or as accurate. Anymore, gas chromatography is universal in the quantitative and qualitative analysis of complex chemical compositions and the purification of chemical compounds. It’s also generally used to manage industrial processes and in the quality-control testing of products.

Of course, the carrier gases required in gas chromatography, besides having to be either inert or unreactive, must be at least 99.995% pure – higher, occasionally! And that’s where A-OX Welding Supply really proves its value. Now, it’s true, we haven’t been on the scene as long as gas chromatography. But, as a trusted PurityPlus® partner producer-distributor, we’ve been providing chemical researchers and diverse industries with carrier gases of the utmost purity achievable for years now. We guarantee it, too. Why? Because A-OX Welding Supply, like all of the 600 PurityPlus® partner gas production facilities across the states, is rigorously inspected and certified every year by a trusted independent third-party organization. Our Sioux Falls 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), principally – depends on the sort of detector being used and the chemical components being analyzed. Normally, we supply gases suitable 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 Sioux Falls customers also depend on us providing the carrier gases they need when they need them. Local availability means too that our customers have ready access to our technical learning and can better cultivate the kind of close relationship with us that fulfills the objectives of both parties.
