Analyzer with fluid pressure control device

摘要

A fluid pressure control device (102), including a pressurized fluid inlet (112), a first valve (130) in fluid communication with the pressurized fluid inlet (112) and controlling the flow of fluid from the pressurized fluid inlet (112), a first pressure measurement device (154) detecting a fluid pressure downstream of the first valve (130), and a controller (140) electrically coupled to the first valve (130). The first pressure measurement device (154) causes the controller (140) to operate the first valve (130) such that a fluid downstream of the first valve (130) is maintained at a substantially constant pressure.
