Abstract

A liquid pulsation dampening system for preparative chromatography is disclosed. In one implementation, the system effectively dampens liquid pulsation while minimizing holdup volume and maximizing the effective dampening range. The liquid pulsation dampening system comprises disc spring washers (also known as belleville spring washers) which are compressed by liquid pulsation though an inert diaphragm, a liquid pressure transmitter and a piston.
