USHA C18-N Column Silica Gel Chromatography

The C18 column is a high-purity hplc column that exhibits excellent peak shapes for a wide range of compounds. This column allows for a shorter diffusion path and nearly double the efficiency compared to traditional fully porous silica particles.

It can be used to enhance the performance of both traditional HPLC systems and UHPLC systems and is compatible with 2 µm inlet frits, so traditional solvents and sample preparation techniques can be used.

universal N-C18 5UM 50X3.0 MM HPLC Column

Features and Applications:

* Unique bonding mode, can achieve 100% water phase condition.


High purity, general purpose Octadecyl (C18) phase with wide selectivity. Recommended for the reverse phase separation of acidic, basic, or neutral compounds.

Stable performance of reversed-phase medium. High separation efficiency, can separate various substances containing non-polar groups such as proteins, peptides, amino acids, nucleic acids, steroids, lipids, fatty acids, sugars, plant bases, etc.
