Column Packing
MilliporeSigma™ Supelco™ Sigma-Aldrich™ Silica Gel, Spherical, 40-75 μm
High purity grade silica gel offers the lowest moisture content, tightest particle size distribution, minimal impurities and greatest lot-to-lot consistency which results in greater reproducibility of the separation process.
MilliporeSigma™ Supelco™ Silica Gel orange with moisture indicator free of heavy metals
Silica gel orange (Drying pearls Orange) is a commonly employed drying agent.
MilliporeSigma™ Supelco™ Sigma-Aldrich™ Silica Gel, Technical Grade, 70-230 mesh
For preparative liquid chromatography
MilliporeSigma™ Supelco™ Sigma-Aldrich™ Silica Gel, High-Purity Grade, 230-400 mesh
For flash chromatography
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™ Supelco™ Discovery™ DSC-SCX SPE Bulk Packing
Silica support allows for use with very organic solvents (no shrinking/swelling). Excellent capacity (0.8 meq/g) for cleaning up solution phase combinatorial chemistry reactions (removing target molecules from reaction by-products and excess reagents).
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ Q, 80-100 mesh
Porapak™ porous polymers are spherical beads with consistent particle size, porosity, and surface area that help to insure analytical precision and accuracy.
MilliporeSigma™ Supelco™ Carbopack™ Adsorbent, Matrix Carbopack™ C, 80-100 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™ Dowex™ 1X8 Chloride Form, 50-100 mesh
This ion-exchange resin has not been specially processed nor cleaned. It is suggested that it be treated to a suitable preliminary elution and wash.
MilliporeSigma™ Supelco™ Carbopack™ Adsorbent, Matrix Carbopack™ B, 60-80 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™ Carbosieve™ Adsorbent, Matrix Carbosieve™ S-II, 60-80 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. Hydrophobic (can be used in high humidity environments)
MilliporeSigma™ Supelco™ Carbosieve™ Adsorbent, Matrix Carbosieve™ S-III, 60-80 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. Hydrophobic (can be used in high humidity environments)
