Leading manufacturer and developer of chromatography columns and accessories, Restek, recently published an article focused on the Petroleum and Petrochemical industry titled: Alternative Carrier Gases for ASTM D7213 Simulated Distillation Analysis by Katarina Oden, Barry Burger and Amanda Rigdon. In the article the authors discuss Simulated Distillation (SimDist) and the carrier gases that can be used in this GC method.
Pressure Swing Adsorption (PSA) nitrogen generators are capable of producing high purity nitrogen gas from a single simple commodity, air. This purity can also be acquired through cryogenic systems, however, these are considerably more complex and expensive so can only be justified where consumption is extremely high.
One of the core technologies in many nitrogen gas generators today is Pressure Swing Adsorption (PSA), using Carbon Molecular Sieve (CMS) adsorbent. The PSA process using CMS is a highly efficient method of generating high purity nitrogen gas from compressed air.

For GC carrier gas it has long been assumed that there are only two viable options, helium or hydrogen. In recent times, however, there has been more and more evidence revealing the proficiency of nitrogen as a suitable carrier gas for GC.
