Title:
TRACE COMPONENT ANALYZER
Document Type and Number:
Japanese Patent JP3046675
Kind Code:
B2
Abstract:
PURPOSE: To obtain a device for analyzing a trace of constituents which can perform measurement accurately and highly sensitively even if a great amount of a sample liquid is poured by continuously mixing the sample liquid which is poured into a reaction reagent and the reaction reagent which bypasses a sample-pouring part at an exit of the sample-pouring part.
CONSTITUTION: At an exit of a sample-pouring part 1, a pure water which is poured into a reaction reagent and a reaction reagent which bypasses 19 the pouring part 1 are mixed continuously. The mixed liquid is introduced to a reaction machine 4 and is subjected to mixing and reaction. Then, the liquid is cooled by a cooling coil 13 and is introduced to an absorbance meter which is used as a detector 14 for measuring absorbance, thus obtaining silicic acid ion concentration according to the peak value. Since all of the pure water which is poured in great quantity are mixed with a color-developing liquid, all of the silicic acid ion within the pure water develop color, thus achieving a normal measurement without causing a peak to be buried under a base line at a low-concentration region of the silicic acid ion or the peak to be split.
