Dependable Excellence for over 20 Years

GL Sciences’ Inertsil columns offer everything you need for your critical separations in all phases of drug development, and something less. Inertsil’s uniquely modified silicas and meticulously engineered column hardware allow our columns to operate at significantly lower back pressures than competitive columns, without sacrificing efficiency. Inertsil’s wide pH compatibility and excellent stability at elevated temperatures make it the ideal choice for your chromatography needs, whether you are using a traditional HPLC system or the latest rapid gradient LC/MS system with precise temperature control.

The Inertsil 3-series represents a major advance in performance over the original Inertsil 2-Series. Inertsil 3-Series phases are based on a purer, higher surface area silica which is specially manufactured to provide maximum bonded phase coverage. The result is a series of columns which provide excellent peak shapes using simple eluents while operating at low pressure.

In addition to ODS-3, we offer our new ODS-4, ODS-Sprint for reduced retention of non-polar compounds, C8-3, Phenyl-3, ODS-EP containing an embedded polar group for increased retention of polar compounds, >CN-3, HILIC, NH2, Diol, and a Polymerically bonded ODS-P phase with unique selectivity for planar compounds, uniquely designed for analysis of 16 priority PAHs in environmental samples but has also found to be useful for pharmaceutical analysis of planar compounds. 

GL Sciences has compiled a vast collection of chromatographic applications data on ODS-3 and their other phases which can assist you in method development. 

Inertsil ODS-3, along with most of the other Inertsil 3-series phases, are available in 3, 5, and 8 micron particle sizes in column configurations ranging from capillary to 50mm ID preparative sizes.

By choosing Inertsil ODS-3, you can be assured that you are using one of the most trusted, popular, and enduring HPLC columns in the history of HPLC.
