New 18-Page Applications Brochure Highlights High Efficiency HPLC Columns from Phenomenex for Enantioseparations of Racemic Pharmaceuticals and Agrochemicals
15 Oct 2006Product news
Chirex brand chiral HPLC columns from Phenomenex are excellent for the enantiomeric resolution of a wide variety of chiral pharmaceuticals and agrochemicals.
A diverse selection of sophisticated chiral selectors are covalently bound to high efficiency 5µm silica to produce some of the most versatile and enantioselective chiral columns available. These rugged columns provide superior analytical separations with respect to capacity, speed and resolution. Scale-up to semiprep and preparative separations is straightforward. Chirex phases are highly load-tolerant and can be used with volatile organic solvents to facilitate isolation of the purified antipodes in bulk. Opposite chiral selector phases are available to put trace components first.
Hundreds of chiral applications are listed in this free 18-page applications guide on chiral chromatography.

Capillary ElectrophoresisCapillary electrophoresis (CE) is used to separate molecules based on charge, size and hydrophobicity. Pressure, voltage or a vacuum is used to introduce the sample to fused silica capillaries. Fluorescence, UV/Vis, UV or diode array detectors are used to visualize components. Types of CE systems include capillary electrochromatography (CEC), capillary zone electrophoresis and capillary gel electrophoresis.

Flash chromatography systems use small silica gel particles for separation and a pressurized gas for driving the solvent through the column or pre-packed cartridge.

Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors.

Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

This can be done in large quantities or small. Preparative chromatography systems are usually low to medium pressure liquid chromatographs that are semi-automated. Explore a range of preparative columns and fraction collectors.

Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.
