Method and apparatus for qualitative and quantitative analysis of dissolved in aqueous solutions of chemical elements

摘要

The present invention relates to a method and a device for the analysis of dissolved in aqueous solutions of chemical elements by means of spark spectroscopy. Dollars a it is an object of the present invention is a simple sampling and an analysis on small quantities of sample or solutions flowing without significantly changing or to decompose. Furthermore, a long service lifetime of the electrodes are ensured. Dollars a in the invention, the solution itself to be examined, an electrode of the spark gap, in which, viewed over time of the sparks from a by means of an impact sparks and a device is obtained the shield. In the case of an electrical breakdown of the resulting defined plasma, the from of the laser spectrometry known breakdown - effect, which makes possible an optical analysis. The occurring during the breakdown characteristic emission of light is in an optical analyzer lengths shafts specifically, the breakdown period of time can be used for special analysis. The aqueous liquid is introduced into a sample container or of a process is branched off, wherein the measurement of the flow takes place during. The construction of the spectrometer is simple and can be designed to be robust.
