Gazelle UHPLC Column

Orochem Technologies Gazelle UHPLC columns offer the chromatographer significantly increased throughput, low solvent consumption, inline process monitoring, and improved LC-MS results. Gazelle is designed by Orochem Technologies, especially to yield higher sensitivity and reproducibility in less run time. Orochem uses a proprietary silica type A manufacturing process that yields a narrow particle size and pore size distribution, which gives you consistent and reproducible results. The hydrophilic spherical surface is also stable over a wide pH range (2-8) to allow for excellent method flexibility. Applications are in clinical diagnostics labs, pharmaceutical discovery and PK/TK studies.

Chiral Chromatography

Epitomize CSP-2 is based on derivatized polysaccharides that are covalently-bound to silica gel. The best CSP for a given separation depends on several factors. For the racemate, these factors include structure, polarity, and the type and number of functional groups present. Although all of the CSPs are based on polysaccharides, each typically shows a different chiral response for the same racemate. This response can also change dramatically with the selection of mobile phase. Together, these CSPs permit the separation of a very broad range of racemates. Both the CSP-1 and CSP-2 Series can be used in normal phase, polar phase, reverse phase, and SFC. Standard modifiers are TEA, DEA, ethanolamine, TFA, acetic acid, etc. and the use level is typically around 0.1%. Each column is tested before packaging and a chromatogram with test conditions and column performance data is included.
