Chromatography Columns and Cartridges
MilliporeSigma™ Supelco™ Molecular Sieve Adsorbent, Matrix Molecular Sieve 5A, 30-40 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™ HayeSep™ Porous Polymer Adsorbent, Matrix HayeSep™ A, 80-100 mesh
HayeSep™A maybe used for the measurement of carbon dioxide using the on-line gas analyser during the experimental set-up, to use activated carbon as a buffer in biofiltration of waste gases, to ensure a constant supply of contaminants like toluene to the bioreactor for effective biological waste-gas treatment.
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ P, 80-100 mesh
Stainless steel column packed with Porapak™™ P maybe used for the analysis of lipoxygenase reaction products by gas chromatography equipped with flame ionization detectors.
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™ Carbopack™ Adsorbent, Matrix Carbopack™ C, 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™ Sephadex™ LH-20
Store at room temp.
MilliporeSigma™ Supelco™ Amberlite™ IRA-67, Free Base
Previously known as IRA-68.
MilliporeSigma™ Supelco™ Derivatized Silica Gel, 15-40 μm
Prepared by the reaction of silica gel with n-octadecyltrichlorosilane. After hydrolysis of the unreacted chloro groups, hydroxyl groups are blocked with trimethylsilyl groups.
MilliporeSigma™ Supelco™ Silica Gel, High-Purity Grade (7734), 70-230 mesh
For column chromatography
MilliporeSigma™ Supelco™ Amberlite™ XAD1180N, 20-60 mesh
Polymeric adsorbent for hydrophobic compounds: antibiotics, vitamins, amino acids, enzymes; for purification: gallium, myxovirescins, phosphoric acid, riboflavin salts.
MilliporeSigma™ Supelco™ Dowex™ 1X2 Chloride Form, 100-200 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™ HayeSep™ Porous Polymer Adsorbent, Matrix HayeSep™ T, 100-120 mesh
HayeSep™ T was used together with a thermoconductivity detector to study the solubility of trioxane in methanol at different temperatures and to measure the vapour pressure data for this binary mixture.
MilliporeSigma™ Supelco™ Diaion™ HP-20SS
Swelling in toluene is 30%
MilliporeSigma™ Supelco™ Supelpak™ -2SV matrix styrene-divinylbenzene, 20-60 mesh
Supelpak™-2SV is purified Amberlite™ XAD2 that has been specially cleaned and tested for optimal performance in the capturing and extraction of semivolatile organics. Packaged in glass containers.
