Column Protection Extended to Widepore Columns

Phenomenex (USA), research and manufacturer of advanced technologies for the separation sciences, have introduced new SecurityGuard ULTRA offerings to protect widepore (≥200 Å) UHPLC columns typically used in the analysis of biomolecules. The SecurityGuard ULTRA system dramatically extends the lifetime of columns packed with sub-2 micron fully 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 new SecurityGuard ULTRA product is ideal for virtually any manufacturer’s UHPLC, sub-2 micron or core-shell widepore columns including the Phenomenex Aeris widepore XB-C18, XB-C8 and C4 products. 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 widepore guard cartridges have no significant impact on chromatography, backpressure or dead volume.
