Arc Sciences has introduced the Opti-guard EXP guard column cartridge system from Optimise Technologies.
Rated to 20,000psi with hand-tight replaceable cartridges for routine use at UHPLC system pressures, the design connects directly to any UHPLC column with an auto-adjusting titanium hybrid ferrule and Opti-lok EXP fittings, providing repeated zero dead volume connections and allowing for easy exchange between various column types.
The combination of low dispersion and high-pressure capabilities, provide for a negligible effect on retention times, plate counts or peak shapes.
This makes the Opti-guard EXP guard column cartridge system suitable for sub two-micron column protection at UHPLC pressures.
