SAMPLE INTRODUCTION DEVICE FOR ICP EMISSION ANALYSIS

摘要

PPROBLEM TO BE SOLVED: To provide a sample introduction device for ICP emission analysis capable of generating together an atomized sample and a vaporized sample with simple configuration by utilizing for generating a hydride, drain liquid staying in a drain gathering place of a chamber to which sample liquid is sprayed from a nebulizer. PSOLUTION: This sample introduction device has configuration wherein the sample liquid S is sprayed to the inside of a cyclone chamber 1 by the nebulizer 2, and an atomized component is delivered through a delivery port 11 on the ceiling of the cyclone chamber 1, and the drain liquid is recovered in the drain reservoir 13 on a bottom part. In the device, an intermediate reservoir 16 for retaining once the drain liquid is provided on the upper position of the drain reservoir 13 inside the cyclone chamber 1, and hydrochloric acid is introduced into the intermediate reservoir 16 by a hydrochloric acid introduction tube 17, and a hydrogenating agent is introduced into the drain reservoir 13 by a hydrogenating agent introduction tube 19, and the hydride is generated by reacting mixed liquid of the drain liquid flowing down from the intermediate reservoir 16 and the hydrochloric acid with the hydrogenating agent inside the drain reservoir 13.
