Analysis of noble and permanent gases on adsorbent columns

Predicting selectivity characteristics of adsorbent columns is often a wild guess. Yes, we know argon will have less retention than krypton, but how well do adsorbent columns separate noble gases from permanent gases? Can neon and hydrogen be resolved using a porous polymer column or do we have to use more retentive columns, like Molecular […]

Totally serious analysis of N2O – capillary column selection

A few years ago, Jaap wrote a blog, “Can I analyze NO, N2O and NO2 via GC?”, which received a vast response. If you are just starting to dive into the analysis of N2O, scroll through the blog comments where you can find many valuable insights from our blog readers. What I would like to […]
