The Elite-5 is a 5% diphenyl/95% dimethyl polysiloxane stationary phase. It is regarded as a general purpose, low polarity phase that is the most popular GC stationary phase. The Elite-5 is a crosslinked phase in which all residual catalysts and low molecular weight fragments have been removed providing a tight mono-modal distribution and extremely low bleed.
The Elite-5ms phase (5% 1,4-bis(dimethylsiloxy)phenylene, 95% dimethyl polysiloxane) incorporates a phenyl group in the polymer backbone to improve thermal stability, reduce bleed and make the phase less prone to oxidation. This results in inertness to active compounds and extremely low bleed for sensitive MS applications.
The Epic™ line of LC columns is based on high density monomerically bonded phases produced through a proprietary bonding process. Epic HPLC columns are compatible with a wide range of organic modifiers and buffers and stable over a wide pH range. All Epic products use an ultra-high purity metal free silica and undergo strict quality control testing. For flexibility, we offer a wide range of column sizes as well being fully sc…
Under highly aqueous conditions, our novel proprietary bonding chemistry allows the bonded chains to remain fully extended in the mobile phase. Epic™ Polar can retain highly water-soluble compounds such as small organic acids, water-soluble vitamins, purines and pyrimidines, catecholamines and other polar compounds. The Epic Polar column offers improved polar compound retention under RP conditions which has been further refin…
The unique properties of Epic™ Naphthyl places its selectivity between graphitized carbon and alkyl type stationary phases. Epic Naphthyl is a naphthalene-based material, with high bonding density and exhibits strong π-π interaction and charge transfer interactions and performs well for diastereomer separations and non-polar compounds. Epic HPLC and UHPLC columns are compatible with a wide range of organic modifiers and buffe…
