HPLC Guard Columns and Cartridges
YMC America, Inc ODS-AQHG grd 120A 10um 30x10mm
YMC-Pack ODS-AQ is a unique reversed-phase material with both a hydrophobic high carbon loading and a relatively hydrophilic surface Because of the hydrophilic surface ODS-AQ can be wetted with polar eluents It provides chromatographers reproducible retention and excellent peak shape in highly aqueous mobile phases including 100% water This is due to the C18 ligands on ODS-AQ actually being lifted from the surface by the action of the eluents penetrating the silica pores Selectivity on YMC-Pack ODS-AQ can be subtly different from that seen on conventional ODS columns Differences in selectivity are most often encountered when analyzing mixtures of relatively polar compounds Typically longer retention and greater resolution are observed with ODS-AQ Available in both 120 and 200 pore sizes YMC-Pack ODS-AQ is well-suited for analysis and purification of peptides and other biomolecules

Optimize Technologies EXPGuard Column Cartridge, 4.6mm x 5mm, SAX, 3µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
