Guaranteeing Superior-Quality Gases for Gas Chromatography


Ever since gas chromatography was {{introduced more than a century ago, it’s become a requisite analytical tool in quite a few industries, the pharmaceutical and food industries first, perhaps, among them. Face it: almost no other techniques for breaking up and analyzing the components of chemical mixtures are as simple, as effectual, or as exacting. Nowadays, gas chromatography is used virtually everywhere in the quantitative and qualitative analysis of complex chemical compositions and the purification of chemical compounds. It’s also extensively used to control industrial processes and in the quality-control testing of products.

Of course, the carrier gases necessary for gas chromatography, beyond having to be either inert or unreactive, must be at least 99.995% pure – greater than that, on occasion! And that’s where Mississippi Welders Supply Co., Inc. comes in. No, we haven’t been on the scene as long as gas chromatography. But, as a trusted PurityPlus® partner producer-distributor, we’ve been supplying chemical researchers and diverse industries with carrier gases of the highest purity feasible for ages now. We guarantee it, too. Why? Because Mississippi Welders Supply Co., Inc., like all of the 600 PurityPlus® partner gas production facilities countrywide, is thoroughly inspected and certified per annum by a recognized independent third-party enterprise. Our Winona 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), mainly – depends on the kind of detector in use and the chemical components being researched or tested. Generally, we produce gases fitting 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 Winona customers also count on us supplying the carrier gases they need when they need them. Local availability means as well that our customers have convenient access to our technical knowledge and can better establish the kind of close relationship with us that’s mutually advantageous.
