Abstract
A flow cell () includes a plate-shaped bodythat is almost rectangular in a plan view, an introduction portion () that is made of a concave portion formed in the upper surface of the body (), a channel () that is formed inside the body () and has one end connected to the lower end of the introduction portion (), and a delivery portion () that is made of a concave portion formed in the body () and has the lower end connected to the other end of the channel (). The introduction portion () is formed to cause the meniscus of a liquid introduced from an opening to apply, to the liquid, a positive pressure or a negative pressure whose absolute value is smaller than that of a negative pressure applied to the liquid introduced into the channel () by the meniscus of the liquid. The channel () is formed to cause the meniscus of the liquid introduced into the channel () to apply a negative pressure to the liquid. This invention provides a flow cell and a liquid feed system capable of more easily controlling feed of a trace amount of liquid.
