What is an Inline Check Valve?

An inline check valve is a special valve that is placed in the flow path where you wish to limit fluid transfer to one direction. Ideal placement for this fitting is on the effluent side of the column to prevent post-column derivatization agents from flowing back up the column and poisoning the column if your HPLC pump were to shut down. Placement on the post-column reagent line may also be desirable to prevent mobile phase from contaminating the reagent if the auxiliary pump were to fail.
