Fiji Police have purchased themselves a $250,000 Gas Chromatography Mass Spectrometry (GCMS) instrument for their forensic chemistry lab. In line with 2015 capital projects, they decided that the instrument was a worthwhile investment and asserted that it will strongly improve their forensic science capabilities.
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.
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.
Peak Scientific will be displaying its innovative gas generation technology at Arablab, Dubai, Stand No. 363 - Arena Hall and don't miss Dr. Ed Connor's seminar on how to switch your GC carrier gas from helium to hydrogen.
