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.

HPLC Column

Orochem Technologies provides a wide range of traditional liquid chromatography columns for analytical, preparative, and simulated moving bed chromatography (SMB) applications. Our HPLC and semi/prep columns are used globally in clinical diagnostics laboratories, industries (like pharmaceutical, biotech, food, nutraceutical), environmental and forensic testing laboratories.

Prep Chromatography

Orochem Technologies provides a wide range of reverse phase, normal phase and chiral prep/semi-prep HPLC columns. The particle size ranges from 5-50 µm, pore size ranges from 80-300 Å, and various dimensions.

Chiral Chromatography

Orochem Technologies offers a family of polysaccharide-based chiral stationary phases (CSPs) for liquid chromatography under the Epitomize brand name. The CSPs are available in particle sizes from 1.7 microns up to 300 microns, and columns can be ordered in many different configurations for use in UHPLC, HPLC, prep/semi-preparative LC, and simulated moving bed (SMB) chromatography. The Epitomize family of chiral stationary phases is composed of two series. Epitomize CSP-1 is based on derivatized polysaccharides that are coated onto modified silica gel.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.

Flash Chromatography System

Flash Chromatography is a rapid form of preparative column chromatography based on optimized pre-packed columns through which are pumped solvent at a high flow rate. It is a simple and economical approach to preparative LC. Orochem provides two types of flash columns. One type is using polypropylene. It is safer than glass columns, with no risk of breakage. Another type is the ISOSPEED flash column; the column is made of stainless steel, which is compatible with higher flow rate and pressure. All Orochem’s flash columns are packed with symmetrical sorbent compression to ensure improved separation and reproducibility.
Orochem Technologies is partnering with Santai Science to offer SepaBean™ machine flash chromatography systems in the Midwest. Santai Science was established in 2004 and focused on developing and providing separation and purification systems. SepaBean™ does more than basic function of separation and purification, the flash chromatography system provides innovative approaches to technology learning and knowledge sharing.
