Raptor 1.8 μm LC columns unleashed superior Raptor performance on UHPLC analyses, and now Restek has released EXP UHPLC guard column cartridges made specifically for Raptor 1.8 μm columns.

These new guards provide extreme protection from particulates and matrix contamination, extend the lifetime of already rugged and long-lasting Raptor columns, and are proven to withstand the same UHPLC pressures as their analytical column counterparts. UltraShield filters are available for filtering out particulates, minimizing extra column volume, and maximizing sample throughput when using SPE, SLE, or other extensive sample preparations—but new Raptor EXP UHPLC guard column cartridges are an especially valuable alternative when using dilute-and-shoot or other minimal sample preparation techniques.
