Guaranteeing Top-Quality Gases for Gas Chromatography


Since gas chromatography was first applied better than a century ago, it’s become an essential analytical tool in a number of industries, the pharmaceutical and food industries chief among them. Face it: few other techniques for separating and analyzing the components of chemical mixtures are as effortless, as effectual, or as precise. Today, gas chromatography is omnipresent in the quantitative and qualitative analysis of complex chemical compositions and the purification of chemical compounds. It’s also widely 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 American Welding & Gas, Inc. proves invaluable. Now, it’s true, we haven’t existed as long as gas chromatography. But, as an esteemed PurityPlus® partner producer-distributor, we’ve been furnishing chemical researchers and various industries with carrier gases of the utmost purity feasible for years now. We guarantee it, too. Why? Because American Welding & Gas, Inc., like each one of the 600 PurityPlus® partner gas production facilities across the nation, is fastidiously inspected and certified annually by a respected independent third-party agency. Our Indianapolis customers will vouch for the purity we deliver.

Which carrier gas we deliver – helium (He), argon (Ar), nitrogen (N2), carbon dioxide (CO2), or hydrogen (H2), principally – is influenced by the type of detector employed and the chemical components being assessed. Typically, we offer 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 Indianapolis customers also rely on us delivering the carrier gases they need when they need them. Local availability means as well that our customers have quick access to our technical know-how and can better foster the kind of tight relationship with us that’s beneficial to both parties.
