摘要
A pumping apparatus for a high performance liquid chromatography system (350) is disclosed. The pumping apparatus comprises a piston (1) for reciprocation in a pump working chamber (3) to compress liquid in the pump working chamber (3) to a high pressure at which compressibility of the liquid becomes noticeable. At least one of the piston (1) and the pump working chamber (3) is at least partially coated with or comprised of silicon carbide.
