    摘要: A flow controller for use with a liquid chromatography detector. The flow controller includes a flow channel comprising an inlet portion, a control channel portion in communication with the inlet portion, and an outlet portion in communication with said control channel portion. The control channel portion has a cross-sectional area smaller than a cross-sectional area of a drift tube of the liquid chromatography detector for channeling the flow of droplets through the smaller cross-sectional area. The flow controller is shaped and sized to reduce pressure fluctuations and turbulence in the droplet stream of the liquid chromatography detector.
