PURPOSE:To enable determination of respective elements by coupling liquid chromatograph and a high frequency induction coupling plasma emission analysis device. CONSTITUTION:The gaseous Ar supplied into a nozzle 2 atomizes the solvent sucked up by a solvent sucking up pipe 3 in the stage of gushing from the nozzle 2 into an outside cylinder 1 and blows into the cylinder 1. The atomized solvents rides in the flow of the gaseous Ar and is supplied through the central pipe of a plasma torch T into a plasma flame P. The outflow liquid from a chromatogram column C rides in the flow of the solvent and is fed into the nozzle 2 by which the liquid is atomized together with the solvent and is supplied into the flame P. The flame P is spectrally analyzed by a spectroscope SP and the spectra are detected by the photodetecting elements disposed in the emission line positions of the elements to be detected on the spectra. The outputs from the respective photodetectors are inputted into a data processing unit D, and the intensity change of the emission line of the element to be detected is recorded with a recorder R. The ratio and total amt. of the constituting elements are thus known by each component. |
