Ensuring Finest-Quality Gases for Gas Chromatography


Since gas chromatography was {{introduced well over a century ago, it’s become a requisite analytical tool in many industries, the pharmaceutical and food industries among the principal ones. Face it: almost no other ways of splitting up and analyzing the components of chemical mixtures are as simple, as effectual, or as accurate. Today, gas chromatography is used virtually everywhere in the quantitative and qualitative analysis of complex chemical mixtures and the purification of chemical compounds. It’s also widely 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 – higher, sometimes! And that’s where Weldstar Specialty Gases truly 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 providing chemical researchers and assorted industries with carrier gases of the highest purity feasible for years now. We guarantee it, too. Why? Because Weldstar Specialty Gases, like all of the 600 PurityPlus® partner gas production facilities countrywide, is thoroughly inspected and certified per annum by a recognized independent third-party agency. Our Northern Illinois 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 type of detector in use and the chemical components being investigated. Normally, 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 Northern Illinois customers also count on us having the carrier gases they need when they need them. Local availability further means that our customers have speedy access to our technical learning and can better cultivate the kind of personal relationship with us that’s mutually beneficial.
