Reversed Phase

Reversed Phase Columns from Daicel

Reversed phase versions have been developed by Daicel specifically for aqueous-organic mobile phases. They are suited for applications where the sample is presented in aqueous media (e.g. biological samples) or for samples that require flexibility in term of pH range. These columns are also frequently used in LC-MS applications.

Reversed phase columns include:

• CHIRALPAK AD
• CHIRALPAK AS
• CHIRALPAK AY
• CHIRALPAK AZ
• CHIRALCEL OD
• CHIRALCEL OJ
• CHIRALCEL OX
• CHIRALCEL OZ

These have the same coated chiral selector as found in the normal phase stationary phases, however in comparison, they use a different bonded silica as the base material which stabilises the CSP.
