HarmonyTM C18 is an identical selectivity to the Waters Symmetry® C18 HPLC column. Many chromatographers use HarmonyTM when looking for a Symmetry® equivalent. HarmonyTM will offer long column lifetime and excellent reproducibility. HarmonyTM is engineered to the tightest specifications and is available in large scale bulk.
Neptune™ dC18 is an alternative to the Waters Atlantis® dC18 material for reverse phase chromatography. In many cases Neptune™ has shown better retention and a longer column lifetime than the Atlantis®. Enhanced polar compounds will be retained with complete compatibility with aqueous mobile phases. Excellent for LC/MS and gradient research. Neptune™ phases are available in 3 micron, 5 micron, and 1.8 micron size particles:
Nucleosil C8, manufactured by Macherey- Nagel, Germany, is spherical totally porous silica bonded with octyl silanes and is available in a wide range of pore sizes and particle sizes. It has been cited extensively in the literature and is very well regarded in the chromatography community. Nucleosil is well characterized and reproducible. ES Industries has extensive experience with Nucleosil packings and manufactures the highest quality Nucleosil columns available.
The Sonoma line is an equivalent to Phenomenex Luna™. Sonoma C18(2) is equivalent to Luna C18(2). Excellent efficiencies, peak shape and resolution are obtained for virtually all Luna™ HPLC applications. A range of particle sizes offers amazing versatility for capillary and LC/MS to prep and process scale applications. ES Industries has developed a line of Sonoma stationary phases equivalent to Phenomenex Luna stationary phases. The new Sonoma phases include C18, C8, HILIC, NH2, SCX and PFP.
The Spherisep SCX is an equivalent to Waters Spherisorb® SCX. Excellent efficiencies, peak shape and resolution are obtained for virtually all Waters Spherisorb® HPLC applications from high quality Spherisep HPLC columns. Range of particle sizes offers amazing versatility for capillary and LC/MS to prep and process scale applications.
The StarRise™ C18 is an identical selectivity to the Waters SunFire™ C18 materials. StarRise has a long column lifetime and excellent reproducibility. StarRise columns provide symmetrical peaks for improved resolution and quantization of acidic neutral and basic compounds a low and intermediate pH range. StarRise is available in many particle sizes as well as preparative bulk.
