Uniform pore size distribution
A unique bonding process to ensure that the stationary phase is more stable in aqueous organic mobile phases
Suitable for LC/MS analysis of water-soluble polar compounds.

Choose the Right Column

Before choosing a chromatographic column, it is important to understand your sample and impurities thoroughly, including their types, structures, polarity, acidity/basicity, molecular weight, etc.

If the sample is polar and weakly acidic, you can choose a C18 column for detection under 100% acidic aqueous conditions. This requires selecting a chromatographic column that can withstand 100% pure water and retains polar compounds well.

If the sample is too polar or highly acidic, you can choose CN, NH2, or silica gel columns, HILIC (hydrophilic chromatography), or use a combination of C18 with strong ion-pair reagents or strong ion exchange chromatography columns.

For alkaline samples, you can choose high-purity silica gel columns (which lack metal impurities and have end-capped silica gel) or some modified C18 columns (such as polar embedding or alkaline deactivation techniques). These options can reduce the tailing of alkaline compounds.

If alkaline compounds are highly polar or strongly alkaline, you can choose a wide pH range C18 chromatographic column for detection at high pH values.
