Silica-based Columns (Others)

E-411

> Column packed with silica gel without chemical modifications

5C8

> Use when the retention capacity of C18 is too strong or that of C4 is too week

> Applicable to ion pair chromatography, because of its rapid mass transfer and equilibrium

> Corresponds to USP L7

5C4

> Use when the retention capacity of C18 or C8 is too strong

> Corresponds to USP L26

5CN

> Utilizes reversed phase interaction and π-electron interaction to separate regioisomers, which typically cannot be separated with ODS, C8, or C4 columns

> Corresponds to USP L10

5NPE

5PYE

> Utilizes several types of interactions based on π-electrons to separate structural isomers

> 5NPE corresponds to USP L67

5SIL

> Uses high purity silica (99.99% or higher)

> Suitable for normal phase analysis using a nonpolar organic solvent

> Corresponds to USP L3

5NH

> Suitable for saccharides analysis by hydrophilic interaction chromatography (HILIC)

> Corresponds to USP L8
