Pittcon Workshops on New Applications for UHPLC & Biofuels Analysis Presented by Phenomenex

  Core-Shell Particles Precision Engineered for Protein and Peptide Separations.   Core-shell particle technology provides striking increases in peak capacity and resolution at lower backpressure, giving chromatographers the ability to achieve ultra-high performance on ANY system, HPLC or UHPLC. A uniform porous silica layer is grown around a solid, spherical silica core, providing effective retention and selectivity with improved resolution, speed, and recovery. Next, optimizing the pore size and shell thickness for intact proteins or smaller peptide fragments provides well-defined depth penetration of biomolecules leading to maximum separation power.

SecurityGuard ULTRA offers a convenient and economical way to extend core-shell, sub-2µm, and other UHPLC column lifetimes SecurityGuard™ ULTRA dramatically extends UHPLC column lifetime and is ideal for virtually any manufacturer's UHPLC, sub-2µm or core-shell columns. SecurityGuard ULTRA protects against the damaging effects of chemical contaminants and microparticulates introduced by the sample, mobile phase or system, which can negatively impact column lifetime, method sensitivity, quantitation and peak identification. By reducing the frequency of column replacements, as well as the need for troubleshooting and system down time, SecurityGuard ULTRA saves chromatographers time and money. Pressure-rated up to 20,000 psi (1,378 bar), these guard cartridges have no significant impact on chromatography, backpressure or dead volume. To watch how easy it is to install SecurityGuard ULTRA visit the product webpage. SecurityGuard ULTRA provides the following advantages: Virtually no change in chromatography Easy cartridge replacement Universal fit compatible with majority of UHPLC column endfittings Pressure rated up to 20,000 psi. Phenomenex also offers an interactive web application where users can enter their UHPLC, sub-2µm or core-shell column information to find the most appropriate column protection system.
