Ensuring Finest-Quality Gases for Gas Chromatography


Since gas chromatography debuted more than a century ago, it’s become a necessary analytical tool in quite a few industries, the pharmaceutical and food industries chief among them. Face it: almost no other ways of separating and analyzing the components of chemical mixtures are as effortless, as effective, or as precise. Nowadays, gas chromatography is omnipresent in the quantitative and qualitative analysis of complex chemical mixtures 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 necessary for gas chromatography, besides having to be either inert or unreactive, must be at least 99.995% pure – more, occasionally! And that’s where Coastal Welding Supply comes in. No, we haven’t existed as long as gas chromatography. But, as a respected PurityPlus® partner producer-distributor, we’ve been providing chemical researchers and various industries with carrier gases of the maximum purity attainable for some time now. We guarantee it, too. Why? Because Coastal Welding Supply, like all of the 600 PurityPlus® partner gas production facilities countrywide, is scrupulously inspected and certified annually by a respected independent third-party enterprise. Our Beaumont 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), primarily – depends on the kind of detector being used and the chemical components being evaluated. Typically, we supply 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 Beaumont customers also rely on us providing the carrier gases they need when they need them. Local availability further means that our customers have quick access to our technical proficiency and can better foster the kind of close relationship with us that’s beneficial to both parties.
