Column Packing
MilliporeSigma™ Supelco™ Carbotrap™ Adsorbent, Matrix Carbotrap™ B, 20-40 mesh
Granular. Friable. Used for molecules with an analyte size relative to C3-C20+ n-alkanes. Hydrophobic (can be used in high humidity environments).
MilliporeSigma™ Supelco™ HayeSep™ Porous Polymer Adsorbent, Matrix HayeSep™ S, 60-80 mesh
HayeSep™ S was used for the analysis of hydrocarbons to check the microbial production of propane and ethane in the deep marine sediments. It was also used for methyl acetate hydrogenolysis activity experiments which were performed in a gas flow set-up to study the relation between reduction temperature and activity in copper catalysed ester hydrogenolysis and methanol synthesis.
