Commercially Equivalent Phases

Search ES Industries Products

At ES Industries, we have developed several lines of Commercially Equivalent Phases. ES Industries’ expertise in surface modification, bonding technology, and column packing technology has enabled us to develop high-quality replacements for commercially available columns. In many cases, the ES Industries developed Commercially Equivalent HPLC columns that provide superior performance and reliability when compared to the original commercial HPLC columns.
HyperSelect HPLC Columns

The HyperSelect line is an alternative to Thermo Fisher Hypersil™. The most popular is the ODS; ES Industries offers the HyperSelect ODS column with identical selectivities in both 3 and 5-micron particles. In addition, the HyperSelect is available as BDS-C18, BDS-C8, end-capped C8, non-end-capped C8, end-capped phenyl, non-end-capped phenyl, silica, TMS, amino, non-end-capped cyano, end-capped cyano, SAX, and SCX. In addition, we also offer an alternative to Hypersil Gold and HyPurity product lines. Excellent efficiencies, peak shape, and resolution are obtained for virtually all Hypersil HPLC applications from high-quality HyperSelect HPLC columns. In addition, the range of particle sizes offers impressive versatility for capillary and LC/MS to prep and process scale applications.

MacroDac HPLC Columns

MacroDac™ is an excellent alternative to W.R. Grace VYDAC® wide pore C18 chromatography media. MacroDac™ C18 is the ideal medium for high-performance reversed-phase chromatography of proteins, peptides, and other large molecules that had previously been difficult to separate by reversed-phase HPLC procedures. The large pores of the 300Å silica allow polypeptide molecules complete access to the interior of the silica pores. MacroDac™ C18 reversed-phase material consists of octadecyl aliphatic groups bonded to the surface of 300Å pore diameter silica. The unique process by which we manufacture MacroDac™ C18 provides for an HPLC media with very high purity synthetic silica and carefully controlled characteristics. The hydrophobic (reversed) phase is attached to the silica using polyfunctional octadecylchlorosilanes resulting in cross-linking, or polymerization of the hydrophobic phase.
