Restec Raptor EXP UHPLC guard column cartridges

The Restec Raptor EXP UHPLC guard column cartridges provide protection from particulates and matrix contamination, especially when using dilute-and-shoot or other minimal sample preparation techniques.

The guard column cartridges for Raptor 1.8 µm columns withstand the same UHPLC pressures as their analytical column counterparts. UltraShield filters are available for filtering out particulates, minimising extra column volume and maximising sample throughput when using SPE, SLE or other extensive sample preparations — but new cartridges are a valuable alternative when using dilute-and-shoot or other minimal sample preparation techniques.
