Description
Technical field
The utility model relates to a kind of quality control and analytical instrument, particularly relates to a kind of analytical instrument of water quality, is convenient to the operation to water analysis, reduces error rate, improves analysis efficiency.
Background technology
Water analysis method can be divided into qualitative analysis and quantitative test.Wherein quantitative test can be divided into chemical analysis and instrumental analysis again.Spectrophotometric method and electrochemical methods are two kinds of analysis means that instrumental analysis is used usually.
Spectrophotometric method is absorbance by measuring measured matter light in certain wave strong point or a wavelength range or luminous intensity, this material is carried out to the method for qualitative and quantitative analysis.Its analysis result meets Lambert-Beer's law (Lambert-Beer).Such as: Chinese utility model patent ZL 201120351880.9 discloses a kind of multispectral water-quality analyser, it comprises water quality detection part, water analysis part and power module, water quality detection part comprises camera bellows, be positioned at the light source generator of camera bellows, testing liquid takes up container and color sensor, light source generator sends white light and shone testing liquid, the color of liquid is thrown on color sensor.Water analysis part, by the collection of data and the process to data, is translated into the parameter of water quality, is judged the content value of compound in reagent by the chromatogram value in detection of reflected past.And for example: Chinese utility model patent ZL 201120371681.4 discloses a kind of water quality analytical system, comprise as the peristaltic pump of fluid driver, multi-channel direction selecting valve, liquid capacity-fixed pipe, air insulated pipe, reaction-detecting unit, detector of liquid, some connecting lines and some reagent bottles, described peristaltic pump can fluid in positive and negative bi-directional drive water quality analytical system, and described reaction-detecting unit comprises reaction vessel, upper stop valve, lower stop valve, heating arrangement, light emission module and opto-electronic receiver modular converter.
Electrochemical methods (electrochemical analysis) is the important component part of another kind of instrumental analysis.It is electrochemical properties according to material in solution and Changing Pattern thereof, is based upon with on the basis of the quantitative relation between electrical quantities and measured matter tittle such as current potential, conductance, electric current and electricity, component is carried out to the instrument analytical method of quantitative and qualitative analysis.Electrochemical methods is divided into three types, and the present invention uses a wherein topmost type: potentiometry.Potentiometry is with an indicator electrode and a contrast electrode and test solution constitutional chemistry battery, measures the electromotive force of battery, carry out the method analyzed according to this under zero current condition.Material quantitative analysis method is measured by potential electrode current potential.If electrode potential E can be determined, then can obtain activity or the concentration of this material.The activity of detected water sample or the relation between concentration and the current potential E recorded can state E=E with Nernst mathematical way
0+ slope log a
i.Wherein E0 and slope are constants, a
iwhat represent is ion concentration.Such as: Chinese utility model patent ZL201220408293.3 discloses a kind of Portable water-quality analysis instrument, comprise analog measuring circuit, digital conversion circuit, microprocessor, dissolved oxygen electrode, conductance electrode, PH electrode, contrast electrode are connected with analog measuring circuit respectively, analog measuring circuit is connected with digital conversion circuit, digital conversion circuit is connected with microprocessor, and microprocessor is connected with memory module, touch-control module, display module and on-line detecting system respectively.
No matter adopt which kind of method, needs all more or less relate to detection reagent, especially adopt the water analysis that chemical method detects, relate to number of chemical reagent, easily mix up and misapply the deviation even mistake causing water analysis in testing process.
