Inertsil columns were developed by GL Sciences in 1986 for sample separations using high-performance liquid chromatography. Starting with Inertsil ODS, a new type of bonded silica was produced providing unmatched performance and reproducibility. Further refinements of evolved silica and the introduction of new phases have allowed Inertsil to achieve industry leading performance for analyte separation to become one of the most highly used columns for HPLC.

Inertsil ODS-3 is still GL Sciences’ most popular phase and continues to be used widely and reliably for long-established methods in pharmaceutical, and contract research labs. Inertsil ODS-3 columns have a relatively strong retentivity compared to commercially available ODS columns. In addition, the introduction of higher surface area si...
Inertsil ODS-3V offers all of the outstanding chromatographic benefits of Inertsil ODS-3 with the added benefit of a more thoroughly documented, validated QC procedure consistent with the demands of GLP/GMP compliance. Each Inertsil ODS-3V is delivered with a Manufacturer‘s Validation Certificate showing the detailed results of every QA ...
Inertsil ODS-2 columns have a pore size of 150 Å offering symmetric peaks for bases, acids with low pressure. When Inertsil ODS-2 was introduced in 1987s, this HPLC transformed the entire industry. Inertsil ODS-2 was the first HPLC phase created using ultra high purity silica, which produced superior base deactivation. Inertsil ODS-2 is o...
The same base silica gel and bonding technology that is used for Inertsil ODS-3 is also employed for Inertsil C8-3. The difference between the two phases is just the length of the hydrocarbon ligands. 10 μm particle size columns are also available to meet the requirement of various pharmacopeia methods. We recommend InertSustain C8 column...
Inertsil C8 columns have a pore size of 150 Å and it is recommended for rapid analysis of highly hydrophobic compounds. We recommend InertSustain C8 or Inertsil C8-4 columns for all new method development. Specifications • Silica : 2 Series High Purity Silica Gel • Particle Size : 5 μm • Surface Area : 320 m2/g • Pore Size : 150 ...
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-sp...
Just like InertSustain Phenyl, Inertsil Ph-3 has phenyl groups directly bonded to the silica gel which provides pure reverse phase characteristics that are critical to resolving highly polar compounds like acidic and basic pharmaceuticals. The near perfect phenyl phase coverage on this material results in symmetric, narrow peaks for even ...
Inertsil Ph has phenethyl groups bonded to silica gel which offers weak pi-pi interactions. As it is modified with phenethyl groups, hydrophobic interactions between alkyl chain and analytes play an important role in separation as well as π-π interactions. To change the selectivity or elution pattern drastically, InertSustain Phenyl is re...
Inertsil NH2 amino column 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 ana...
HILIC is, abbreviated name for Hydrophilic Interaction Chromatography, and it was developed as an alternative to reversed phase chromatography for highly polar compounds. Inertsil HILIC is the column which chemically bonded with diol group, and it provides excellent peak shape for neutral and basic compounds. In HILIC mode, generally when...
Inertsil ODS columns are general purpose, reversed phase C18 columns available in 5 μm and 10 μm particle sizes. It was the first ODS bonded phase introduced from GL Sciences back in 1986. We recommend InertSustain C18 or Inertsil ODS-4 columns for all new method development. Specifications • Silica : Spherical Silica Gel • Parti...
GL Sciences offers a polymerically bonded ODS-P phase which provide high steric selectivity for separation of planar and non-planar compounds. nertsil ODS-P columns are also ideal for the HPLC analysis of 16 PAH compounds, listed as target pollutants by the US EPA. Specifications • Silica : 3 Series High Purity Silica Gel • Particle ...
Inertsil ODS-EP contains a polar functional group embedded between the silica surface and the C18 group. The embedded polar group makes the C18 phase stable in 100 % aqueous eluents without "phase collapse." This phase is also extremely "base deactivated" and provides superior peak shape for acids and bases in organic eluents as well a...
Inertsil ODS-SP is super base deactivated and optimally bonded to retain hydrophilic compounds without excessive retention of hydrophobic compounds achieving better separations faster than before. As the carbon load of Inertsil ODS-SP is relatively low, it is compatible with 100 % aqueous eluents and offer faster equilibration of column f...
Inertsil ODS-4 columns have proven superior worldwide for analysis of strong pharmaceutical bases, acids, chelating compounds, and zwitterions. The long-awaited validated Inertsil ODS-4V has now been added to our product lineup. Each Inertsil ODS-4V is delivered with a Manufacturer’s Validation Certificate showing the detailed results ...
Inertsil ODS-4 delivers the same extreme inertness to any type of compounds just like InertSustain C18 along with unprecedented stability under 100 % aqueous mobile phases for qualitative and quantitative analysis. However, as the base silica gel and carbon loading are different on Inertsil ODS-4, differences in selectivity can be observe...
Ultra High Retentivity Ideal for Separation of Basic Molecules & its Related Substances, Process Impurities Inertsil ODS-HL employs a highly inert packing material which provides pure hydrophobic interaction between analytes without generating any secondary interaction delivering sharp peaks. High-Density bonding of C18 phase delivers ...
Inertsil Amide column is bonded of carbamoyl group, and it shows strong retention of highly polar compounds. As shown below, compared to other commercial columns, Inertsil Amide column showed high retentivity. Inertsil Amide column provides excellent performance for those hard to retain compounds using an ODS column with a long lifetime. ...
High inertness — Inertsil columns feature sophisticated surface treatment to provide exceptionally low interference of analyte by surface silanols
