Phenomenex Inc. has introduced new SecurityGuard ULTRA offerings to protect widepore UHPLC columns typically used in the analysis of biomolecules. The system extends the lifetime of columns packed with sub-2 micron porous or core-shell particles by protecting against the damaging effects of chemical contaminants and microparticulates introduced by the sample, mobile phase, or system. These contaminants can also affect method sensitivity, quantitation, and peak identification.
The SecurityGuard ULTA is suitable for any manufacturer's UHPLC, sub-2 micron or core-shell widepore columns. It reduces the frequency of column replacements, as well as the need for troubleshooting and system downtime. Pressure rated up to 20,000 psi (1,378 bar), these widepore guard cartridges have no impact on chromatography, backpressure, or dead volume.
