Abstract

The invention relates to a quantitative sample and dilution analysis device, which comprises a quantitative sampling device, a reaction tank, a dilution water pipeline, a siphon pipeline, a floating-ball liquid-level sensor and a pumping pipeline, wherein the quantitative sampling device causes a water sample to be injected into an outer pipe, and causes the water level to be higher than an inner pipe sleeved inside the outer pipe; therefore, the water sample of the outer pipe can be discharged, so as to obtain the quantitative water sample; the dilution water pipeline provides dilution water for entering the reaction tank; after the water supply of the dilution water pipeline is stopped, the liquid level of the dilution water is reduced to a predetermined height position through the siphonage effect of the siphon pipeline, so as to provide quantitative dilution water, to dispose the height of the floating-ball liquid-level sensor, and to confirm that a fixed volume of dilution water is provided. Therefore, the quantitative water sample is added in the dilution water to be analyzed.

Description

technical field [0001] The invention relates to an automatic analysis device, in particular to a quantitative sampling and dilution analysis device required for analyzing water samples by dilution method. Background technique [0002] In the process of semiconductor factories and chemical factories, various chemical tanks are often used, such as activation tanks, browning tanks, bulking tanks and speeding tanks, etc. The chemical concentration in the chemical tanks is related to the quality of the product. Therefore, in order to increase product yield and maintain quality, it is necessary to regularly check the chemical concentration in the chemical tank. [0003] At present, automatic analysis devices have been used to test the concentration of chemicals in chemical tanks to save manpower. In order to save the use of chemicals and increase the life of the sensing system, generally high-concentration water samples will be processed through dilution procedures. At present Ge...
