We generally recommend the Direct Adaptive Di-Ad™ column connectors instead of a fitting that can be re-swaged each time one of our columns is removed (both standard 4um and 2.o™ phases) to enable a clean connection when changing HPLC columns. The Di-Ad™ allows proper and easy installation of Cogent columns as well as different columns without the hassles of swaged ferrules.
We do not recommend Di-Ad™ or PEEK fittings for UHPLC.
