Ensuring Superior-Quality Gases for Gas Chromatography


Since the time gas chromatography was {{introduced well over a century ago, it’s become an all-important analytical tool in many industries, the pharmaceutical and food industries among the main ones. Face it: few other methods of splitting up and analyzing the components of chemical mixtures are as elementary, as effectual, or as exacting. Anymore, gas chromatography is universal in the quantitative and qualitative analysis of complex chemical blends and the purification of chemical compounds. It’s also widely used to monitor 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 – higher, in some instances! And that’s where Greco Gas comes in. No, we haven’t been here as long as gas chromatography. But, as an esteemed PurityPlus® partner producer-distributor, we’ve been supplying chemical researchers and assorted industries with carrier gases of the utmost purity feasible for a good, long time now. We guarantee it, too. Why? Because Greco Gas, like every one of the 600 PurityPlus® partner gas production facilities across the states, is thoroughly inspected and certified each year by a trusted independent third-party outfit. Our Pittsburgh customers will confirm 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 used and the chemical components being assessed. Generally, we produce 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 Pittsburgh customers also count on us having the carrier gases they need when they need them. Local availability additionally means that our customers have convenient access to our technical capabilities and can better foster the kind of tight relationship with us that’s mutually advantageous.
