Chromatography Columns and Cartridges
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.
MilliporeSigma™ Supelco™ Silica, 99.8%
May contain adsorbed H2O and CO2 which is removable by calcining at >900°C
MilliporeSigma™ Supelco™ HayeSep™ Porous Polymer Adsorbent, Matrix HayeSep™ R, 60-80 mesh
HayeSep™ R was used for GC packed column for quantitation of methanol, ethanol, isopropanol, acetone and ethylene glycol. It was also used in studies investigating plasma stabilization of pre-mixed methane-air combustion using a miniaturized glide-arc reactor integrated into a Bunsen type burner for plasma-activation of fuel-steam mixtures.

MilliporeSigma™ Supelco™ Molecular Sieve Adsorbent, Matrix Molecular Sieve 5A, 60-80 mesh
Molecular sieves are synthetically produced zeolites (naturally occurring aluminosilicate minerals), and are characterized by pores and internal cavities of extremely uniform dimensions.
MilliporeSigma™ Supelco™ Carbotrap™ Adsorbent, Matrix Carbotrap™ C, 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™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ S, 80-100 mesh
Porapak™™ S maybe used in isothermal gas chromatographic analysis of light gases, for detection and separation of CO2, C2H2, C2H4 and C2H6.
