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
