In-line filters are small filter devices installed directly in the solvent or mobile phase path of an HPLC system. Their main purpose is to trap particulates and prevent them from entering critical components such as the column, pump, and detector.
Protect the Column: HPLC columns are very sensitive; even tiny particles can block or damage the column packing.
Prevent Pump Damage: Particulates can scratch pump seals or cause clogging.
Improve Reproducibility: Removing debris ensures smooth flow and stable baseline signals.
Extend Column Life: Prevents early degradation from contaminants.
