Product Description
The Merck ChiraDex guard cartridges 4x4.0mm, 5µm, are used to protect ChiraDex HPLC columns. LiChroCART guard cartridges can be operated together with the matching manu-CART holder 1.51486.0001 upstream of the analytical cartridge column.
Features and Benefits
- Covalently bound beta-cyclodextrin selectors
- Broad enantioselectivity
- Chiral recognition via inclusion complexes and stereoselective hydrogen bonds
- Can be used with simple reverse-phase eluents in many cases
- High-resolution version available for higher separation performance
Additional Notes
ChiraDex utilizes the hydrophobic cavity and hydrophilic openings of beta-cyclodextrin to form diastereomeric inclusion complexes. Enantioselectivity depends on molecular size, substitution pattern, pH, organic content, and temperature. The silica-based material is typically operated within a pH range of approximately 3 to 7.5.
