Phenomenex Inc., a global leader in the manufacture of separation science consumables, announces the addition of regenerated cellulose (RC) syringe filters to its popular Phenex line. By removing particulates from the sample, the filters prevent buildup and blockage of chromatography columns and frits while minimizing wear and tear on injection valves. Sample filtration can ultimately reduce system downtime and component replacement. The new RC membranes deliver clean sample with no detectable leachates and they are compatible with HPLC, GC, IC and CE analysis.

Phenex-RC filters have many advantages over traditional nylon membrane offerings, including wider chemical compatibility. These durable filters offer higher flow rates and perform at greater throughput levels. Phenex-RC filters are also effective for preparation of biological samples including proteins, peptides and other biomolecules.

All Phenomenex Phenex syringe filters are HPLC-tested for extractables and meet quality standards including ISO, DIN and ASTM. The filters are delivered with a certificate of analysis and they are batch-traceable.

"Our quality control and certification programs ensure that these are the best filters on the market, and they are backed by a solid product guarantee," commented JT Presley, brand manager for Phenomenex. "Our new Phenex-RC syringe filters replace a wide variety of membrane types, delivering fast, efficient filtration for improved system performance and results."

Phenomenex is a global technology leader committed to developing novel separation, purification and analytical chemistry solutions for the life sciences and related industries. Phenomenex's core technologies include products for liquid chromatography, gas chromatography, sample preparation, bulk purification chromatographic media, and chromatography accessories and equipment.

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.

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.

Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.FiltrationFiltration and microfiltration are used to separate solids, particulates or large molecules from fluids (liquid or gases) in order to purify the filtrate. Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration, smaller particulates may require additional force for timely separation. Microfiltration equipment includes vacuum filters, as well as positive pressure, crossflow and centrifugal filtration devices.
