Normal Phase HPLC Columns

GL Sciences offers silica-based normal phase HPLC columns optimized for separating polar compounds via adsorption chromatography. Ideal for analyses involving polar solvents and analytes with limited water solubility, these columns include ultra-pure unmodified silica, NH₂, and CN bonded phases. Supported by Inertsil and InertSustain brands, these columns deliver excellent inertness, stable retention, and reproducible performance in challenging separations.

In general, the stability and reproducibility of the Cyano phase available in the market are poor. Many batch-to-batch or lot-to-lot reproducibility issues are occurring at many laboratories. The InertSustain Cyano columns were developed to resolve these problems and are designed using the most modern LC column technology available providing them to be extremely inert, stable ...

InertSustain NH2 shows far superior stability compared to other brand available aminopropyl columns, as our newly developed “Evolved Surface Silica” is chemically bonded with aminopropyl group. Generally, aminopropyl columns are used for applications that are hard to be separated in a reversed phase mode, such as simultaneous analysis of sugars or vitamin E. However, the shift ...

Inertsil Diol column has characteristics of dihydroxypropyl group bonded phase. It shows unique selectivity normal phase mode. The separation mechanism of diol column is featured by hydrogen bonding interactions between diol groups and polar compounds. Diol columns provide an alternative selectivity to silica columns often with increased retentivity. Selectivities of Inertsil ...

Inertsil SIL-100A is a pure silica gel column available in normal phase mode. Because of the high quality of its silica gel, Inertsil SIL-100A achievs separation with sharp peaks and provides high column-to-column reproducibility. This excellent silica gel ideally designed for HPLC is the basis for “Inertsil 3-series” of GL Scineces. GL Sciences is the first company which ...

Inertsil CN-3, Cyanopropryl groups bonded to Silica gel with high density. And it is not only increase difference recognition of hydrophilicity, but also increase the durability. It is difficult to increase the both performance with other previous cyanopropryl columns. Inertsil CN-3 can be cleaned with 100 % aqueous solvent because non-specific adsorption of water effected ...

Inertsil SIL-150A is ultra pure silica gel column, and this ultra pure silica gel contains very low level of metal impurities and is durable and free from dents and cracks which can cause premature column failure. Compared to Inertsil SIL-100A, the silica’s surface area is smaller (320 m²/ g). Retentivity of Inertsil SIL-150A is weaker than that of Inertsil SIL-100A.

Inertsil WP300 SIL is pure silica gel phase with wide pores(300 Å). It is available for analysing compounds including large molecules. As the pore becomes wider, the surface area of silica gel is smaller. Since the interactions between the analyte and silica gel occur on the sIlica surface, smaller surface area means less interactions and faster elution. In the figure below, ...
