For column chromatography
MilliporeSigma™ Supelco™ Silica Gel, High-Purity Grade, 130-270 mesh
For column chromatography
MilliporeSigma™ Supelco™ General Purpose Adsorbent, Matrix Activated Cocounut Charcoal, 20-40 mesh
Activated coconut charcoal (activated carbon) is used extensively as a general purpose adsorbent, especially for purification applications where the trapped compounds do not need to be recovered.
MilliporeSigma™ Supelco™ AmberChrom™ (formerly Dowex™) 50WX4 Hydrogen Form, 200-400 mesh
This strongly acidic cation exchange resin has not been specially processed nor cleaned. It is suggested that it be sujbected to a suitable preliminary elution and wash.
MilliporeSigma™ Supelco™ Amberlite™ IRA-67, Free Base
Previously known as IRA-68.
MilliporeSigma™ Supelco™ Dowex™ 1X8 Formate Form, 200-400 mesh
Dowex™ 1X8, a strongly basic anion exchange resin, has been used as an absorbent in solid phase extraction.
