COSMOSIL C18-AR-II HPLC Columns

Reversed phase Octadecyl group 

Acid Resistance
COSMOSIL 5C18-AR-II packed column features a polymeric type of C18 reversed phase material. The acidic resistance of COSMOSIL 5C18-AR-II is much improved compared with commercially available monomeric type octadecyl stationary phases. It retains high performance even in case of acidic mobile phases commonly used to separate acidic compounds and peptides.

Specifications

Packing Material 3C18-EB C18-MS-II C18-AR-II C18-PAQ

Specific Surface Area approx. 300 m2/g
Stationary Phase Stationary phase C18-MS-II Stationary phase C18-AR-II C18-PAQ
Octadecyl Group
Bonding Type Monomeric Polymeric
Main Interaction Hydrophobic Interaction
End Capping Treatment Near-perfect Treatment
Carbon Content approx. 14.5% approx. 16% approx. 17% approx. 11%
pH Range 2-10* 1.5-7.5* 2-7.5
Feature This phase with a better end-capping treatment offers improved peak shape and separation particularly
for basic compounds.
This phase is recommended for most applications but particularly effective for basic compounds. This phase is recommended for separations requiring acidic mobile phase conditions. It also shows superior molecular shape selectivity to monomeric type C18columns. This phase is designed to offer superior retention of polar compounds and excellent reproducibility in highly aqueous mobile phases, even in 100% aqueous.

Optimum pH range of columns based on silica gel is between 2 and 7.5.
