Metal Filter Products and the LC System

Frits and filters are porous metal products used in virtually all liquid chromatographic (LC) systems. Their function is to prevent unwanted particles from entering the LC system. These particles may come from the sample, the solvent or debris generated by the LC system itself (i.e. pump or injector). Particles entering the LC system may lead to clogging of capillaries, interference with the chromatography by changing chromatographic parameters or disturbance of the detector function.

This white paper describes frits for chromatography, the LC system and gives advice on how to choose the right frit for your LC system.
