Guaranteeing Finest-Quality Gases for Gas Chromatography


Ever since gas chromatography was first applied well over a century ago, it’s become a necessary analytical tool in many industries, the pharmaceutical and food industries among the main ones. Face it: few other ways of splitting up and analyzing the components of chemical mixtures are as simple, as effective, or as exacting. Nowadays, gas chromatography is omnipresent in the quantitative and qualitative analysis of complex chemical blends and the purification of chemical compounds. It’s also generally used to control industrial processes and in the quality-control testing of products.

Of course, the carrier gases needed in gas chromatography, beyond having to be either inert or unreactive, must be at least 99.995% pure – more, sometimes! And that’s where Toll Company truly makes a difference. Now, it’s true, we haven’t been here as long as gas chromatography. But, as a respected PurityPlus® partner producer-distributor, we’ve been supplying chemical researchers and diverse industries with carrier gases of the finest purity attainable for quite a while now. We guarantee it, too. Why? Because Toll Company, like each and every one of the 600 PurityPlus® partner gas production facilities across the United States, is meticulously inspected and certified annually by a respected independent third-party organization. Our Minneapolis 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. Generally, we offer 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 Minneapolis customers also count on us having the carrier gases they need when they need them. Local availability additionally means that our customers have speedy access to our technical expertise and can better foster the kind of close relationship with us that’s advantageous to both parties.
