New 15mm ID Preparative Columns for HPLC and SFC

Preparative chromatography is an extremely powerful technique for the isolation of compounds from complex mixtures. Our new 15mm ID format enables the chromatographer to perform preparative chromatography on most analytical HPLC instruments, thus avoiding the purchase of new dedicated, expensive preparative HPLC equipment. Preparative columns with 20mmID are typically operated on preparative HPLC equipment at flow rates between 12 – 20 mL/min well above the flows possible on an analytical HPLC. The new 15mmID column can operate at flow rates between 6-9 mL/min and offers more than twice the loading amount of semi‐preparative 10mm ID columns. More ....

Epic Polar, 1.8 micron HPLC Columns

Epic Polar 1.8 um - Epic Polar 1.8 um is a high density C18 packing specifically engineered for the retention of polar analytes enabling highly soluble solutes to fully interact with the bonded hydrocarbon phase, even in pure aqueous mobile phases. Under these highly aqueous conditions, this novel proprietary bonding chemistry allows the bonded chains to remain fully extended in the mobile phase. Epic Polar is a true base deactivated reverse phase column and does not contain any undesirable ion exchange or mixed mode characteristics. Click on the link for example applications. More ....

HyperSelect HPLC Columns

HyperSelect™ - The HyperSelect line is an equivalent to Thermo Fisher Hypersil®. The most popular material type is ODS; ES Industries offers the HyperSelect ODS column with identical selectivities in both 3 and 5 micron particles. In addition to the ODS, HyperSelect is available as BDS-C18, BDS-C8, endcapped C8, non-endcapped C8, endcapped phenyl, non-endcapped phenyl, silica, TMS, amino, non-endcapped cyano, endcapped cyano, SAX and SCX. Excellent efficiencies, peak shape and resolution are obtained for virtually all Hypersil HPLC applications from high quality HyperSelect HPLC columns. The wide range of particle sizes offers amazing versatility for capillary and LC/MS to prep and process scale applications. More ....
