Liquid-gas separator for hydride sample injection of inductively coupled plasma (ICP) devices

摘要

Inductively coupled hydride sample injection liquid for the plasma apparatus according to the present invention - a gas separator is one end of the porous membrane tube is inserted into the heat-resistant glass container, and a structure which becomes the container is tilted with respect to the horizontal plane. In addition, one end of the tube inserted into the container is connected to the bent shape of the pipe. As the injection of the sample through the tube with a mixture of NaBH4 chemical reaction of hydrogen and a hydride gas generation, and the gas to pass through the membrane enters the inside of the container. Hydride and the hydrogen gas generated is moved to the plasma along the carrier gas entering the vessel, and does not react with the gas mixture remaining in the container will take the inclined wall through the bent tube quickly discharged through the flow outlet.
