A sample purification apparatus includes a container for separating, with a heavy solution, a mixed sample based on a specific gravity difference and a collector that collects a component in the mixed sample lighter in specific gravity than the heavy solution by receiving a supernatant flowed out from the container. The container includes a flow-out port provided in an uppermost portion of the container and a flow-out path that guides the supernatant flowed out through the flow-out port to the collector. the container has a horizontal cross-sectional area which gradually decreases upward starting from a prescribed height of the container to a height where the flow-out port is located.

Sample purification apparatus and analysis system

A first flow rate adjustment mechanism () and a second flow rate adjustment mechanism () are controlled by a flow rate control unit () so that a carrier gas flows through a first supply path () and a second supply flow rate () at a predetermined flow rate. The flow rate control unit () includes cell flow rate control means () for controlling the first flow rate adjustment mechanism () and the second flow rate adjustment mechanism () so that the flow rate of the carrier gas introduced into a sample cell () in a sparging state, which is a state where the carrier gas is supplied from the first supply path () into a syringe pump (), and the flow rate of the carrier gas introduced into the sample cell () in a normal state.

Measurement device for total organic carbon

A control device controls driving of a pulse motor to cause liquid that is sucked into a syringe in a single suction process to be discharged over a plurality of discharge processes. The control method of the control device is a method that controls driving of the pulse motor so that rotation of a ball screw for executing each discharge process starts from an identical rotational angle position relative to a slit of a coupling.

Liquid feeding device using ball screw, and analyzer

Pure water is sucked from an acid adding flow line into a syringe and discharged from a drain flow line to clean the acid adding flow line, and then a carrier gas from a gas pipe is supplied to the acid adding flow line by the syringe to dry the acid adding flow line. A sample water collecting flow line is also cleaned and dried in the same manner. A TOC measurement flow line is cleaned with cleaning water sucked from a cleaning water flow line into the syringe, then a carrier gas from the gas pipe is supplied to the TOC measurement flow line by the syringe to clean and dry a flow line through which sample water flows in an organic matter oxidative decomposition unit from the TOC measurement flow line.
