C18 HPLC Columns

2.0 µm | 2.7 µm | 5 µm
The first choice for starting a new method.

2.7 µm
Separate compounds that are challenging to resolve or elute early on C18 or other phenyl phases

RP-Amide HPLC Columns

2.0 µm | 2.7 µm | 5 µm
Combining an embedded polar group stationary phase and Fused-Core particles.

Phenyi-Hexyl HPLC Columns

2.0 µm | 2.7 µm | 5 µm
Combining the popular phenyi-hexyl stationary phase and Fused-Core particles.

C8 HPLC Columns

2.0 µm | 2.7 µm | 5 µm
Ideal for non-polar compounds that are reatined too strongly by C18.

ES-Cyano HPLC Columns

2.0 µm | 2.7 µm | 5 µm
Provides stable, reversed-phase packing for basic, acidic or neutral compounds.


2.0 µm | 2.7 µm | 5 µm
Ideal for many classes of polar compounds.

F5 HPLC Columns

2.0 µm | 2.7 µm | 5 µm
Separate closely related compounds.

OH5 HPLC Columns

2.0 µm | 2.7 µm | 5 µm
Pentahydroxy phase for fast analysis of polar compounds.

Peptide ES-C18 HPLC Columns

2.7 µm
Separate high molecular weight compounds such as peptides and small proteins.
