Chromatography Columns and Cartridges
MilliporeSigma™ Supelco™ Carbosieve™ Adsorbent, Matrix Carbosieve™ G, 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. Hydrophobic (can be used in high humidity environments)
MilliporeSigma™ Supelco™ GC Stationary Phase, SP™-2100
A methyl silicone fluid suitable as stationary phase
MilliporeSigma™ Supelco™ HayeSep™ Porous Polymer Adsorbent, Matrix HayeSep™ N, 100-120 mesh
HayeSep™ N was used as a adsorbent for analytical preconcentration of methane which contributes majorly to the greenhouse effect. It was found to have good adsorption capacity, highest overall selectivity and highest enthalpy for methane adsorption as compared to other adsorbents.
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ QS, 100-120 mesh
Porapak™™ QS packed column maybe used for gas-solid chromatographic determination of moisture in lyophilized pharmaceutical products.
MilliporeSigma™ Supelco™ Diaion™ HP-20
Swelling in toluene is 30%
MilliporeSigma™ Supelco™ Dowex™ 1X4 Chloride Form, 200-400 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™ Dowex™ 50WX8 Hydrogen Form, 200-400 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™ 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™ Dowex™ 50WX8 Hydrogen Form, Strongly Acidic, 16-50 mesh
Dowex™ 50WX8 hydrogen form may be used in separation medium for TLC, paper chromatography and LPLC.
MilliporeSigma™ Supelco™ Dowex™ 1X8 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™ Amberlite™ IRA-900 Chloride Form
Amberlite™ IRA-900 chloride form is a macroporous, polystyrenic type 1 resin.
MilliporeSigma™ Supelco™ Ambersep™ 900, Hydroxide Form
Stongly basic (type I) anion exchange resin.
MilliporeSigma™ Supelco™ Porapak™ Porous Polymer Adsorbent, Matrix Porapak™ Q, 50-80 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™ HayeSep™ Porous Polymer Adsorbent, Matrix HayeSep™ Q, 60-80 mesh
HayeSep™ porous polymers, considered second generation materials, are consistent batch-to-batch, with minimal shrinkage and monomer bleed.
