Column Packing
MilliporeSigma™ Supelco™ 44 H2SO4 Coated Silica Gel
Treated silica gels may be primarily employed in the pre-packed multi-layer silica gel columns are available in bulk packages.
MilliporeSigma™ Superspher™ Silica Sorbents
For HPLC of complex mixtures where high peak capacity is required
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ R, 80-100 mesh
Porapak™ R with Amberlite™ XAD-4 maybe useful for chromatographic sampling of polar and nonpolar low-volatility compounds.
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ S, 100-120 mesh
Porapak™™ S maybe used in isothermal gas chromatographic analysis of light gases, for detection and separation of CO2, C2H2, C2H4 and C2H6.
MilliporeSigma™ Supelco™ Dowex™ 50WX8 Hydrogen Form, 100-200 mesh
This resin has not been specially processed nor cleaned. It is suggested that it be sujbected to a suitable preliminary elution and wash.
MilliporeSigma™ Supelco™ Tenax™ Porous Polymer Adsorbent, Matrix Tenax TA, 80-100 mesh
Tenax™ TA is suitable as an adsorbent used for air sampling, it was examined for its potential to form artifacts with Ozone at environmental concentrations, which was then quantitatively analysed using GC-MS analysis. It is also used in adsorbent columns suitable for recovering volatile compounds analysed by GC.
MilliporeSigma™ Supelco™ Carbosieve™ Adsorbent, Matrix Carbosieve™ S-II, 80-100 mesh
Spherical (better packed bed performance than granular particles). Hard and non-friable (pack well, will not break). Highly porous (high surface areas). Used for molecules with an analyte size relative to C2-C5 n-alkanes.
MilliporeSigma™ Supelco™ Diol-Functionalized Silica Gel, Spherical, 40-70 μm
Diol-functionalized silica gel may be used as stationary phase for liquid chromatographic analysis.
