Chiralpak cbh column regeneration
WebCHIRALPAK AGP® has extremely broad applicability for the separation of chiral drugs. The chiral selector is alpha1-acid glycoprotein (AGP). This very stable protein is immobilized onto spherical 5 micrometer silica particles. The CHIRALPAK® AGP column separates enantiomers of an extremely broad range of drug compounds. http://www.hplc.eu/ct.htm

WebBefore disconnecting the column from the HPLC system, flush the column with a mobile phase that does not contain any salts / buffers, e.g. Water/2-PrOH 90/10(v/v). For the storage of the column, it is recommended to fill it with Water/2-PrOH 85/15(v/v). For short storage period, the column can be placed at ambient temperature (<30°C).
