Guaranteeing Finest-Quality Gases for Gas Chromatography


Since the time gas chromatography was {{introduced well over a century ago, it’s become a necessary analytical tool in various industries, the pharmaceutical and food industries among the main ones. Face it: hardly any other ways of separating and analyzing the components of chemical mixtures are as easy, as effective, or as precise. Today, gas chromatography is pervasive in the quantitative and qualitative analysis of complex chemical compositions 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 required in gas chromatography, aside from having to be either inert or unreactive, must be at least 99.995% pure – more, occasionally! And that’s where Sidney Lee Medical & Scientific Gases truly proves its value. Now, it’s true, we haven’t been on the scene as long as gas chromatography. But, as an esteemed PurityPlus® partner producer-distributor, we’ve been providing chemical researchers and various industries with carrier gases of the greatest purity feasible for years now. We guarantee it, too. Why? Because Sidney Lee Medical & Scientific Gases, like each and every one of the 600 PurityPlus® partner gas production facilities nationwide, is thoroughly inspected and certified yearly by a respected independent third-party agency. Our Atlanta, GA 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), principally – depends on the type of detector in use and the chemical components being evaluated. Typically, we produce gases suitable 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 Atlanta, GA customers also count on us delivering the carrier gases they need when they need them. Local availability additionally means that our customers have quick access to our technical proficiency and can better foster the kind of personal relationship with us that’s advantageous to both parties.
