Description
Technical Field
The utility model relates to an analysis and detection instrument technique especially relates to a multi-parameter analyzer.
Background
The colorimetric method is a method which is frequently used in an analyzer, and the principle of the colorimetric method is that a specific light irradiates a reaction tank, a substance to be detected in the reaction tank reacts with a specific reagent added in the reaction tank, and the reacted substance absorbs light to reduce light transmittance. According to the Lambert beer law, the light transmittance is related to the concentration of the object to be measured, and the concentration of the object to be measured can be calculated according to the transmittance of the sample by making a series of standard curves of the concentration and the light transmittance.
In the prior art, the colorimetric analyzer has the following defects:
1. single parameter: most of the current analyzers use a monochromatic LED or a white LED plus a narrow filter as a light source to provide a required specific wavelength, and since the wavelength used by each analyte may be different, the light source with different wavelength needs to be replaced for analyzing different analytes. Most instruments in the market at present are fixed with a light source by one instrument, analyze a parameter, and if a client needs to monitor a plurality of targets, a plurality of instruments need to be used, so that huge purchase cost and maintenance cost are needed, and enough space is needed for placing instruments and equipment.
2. Multi-parameter off-line: the existing multi-parameter colorimetric analyzers in the market are of two types, one type is a spectrophotometer with a complex purchasing structure, different wavelengths need to be switched when one parameter is measured, and the multi-parameter colorimetric analyzers can only be generally applied to laboratory instruments and cannot be used for online environment monitoring. The other type is a fixed multi-light source instrument, wherein a plurality of light sources are fixedly arranged on one side of each light source and are started when needed. The multi-light source instrument has a relatively complex structure, is not suitable for an online instrument, is fixed in light sources, is limited in quantity and position, and intelligently analyzes 2-3 fixed parameters at most.
3. The dilution analysis result has poor accuracy: colorimetric analyzers have a certain measurement range, and when the concentration of an object to be measured exceeds the measurement range, the prior art has two methods for dilution. One is manual input multiple dilution, the analyzer calculates by manually inputting dilution multiple, the control unit controls to inject a certain amount of sample and a certain amount of dilution solution, and the content of the sample is measured after the sample is diluted. One is fixed-time dilution, the analyzer calculates according to the fixed dilution time, the control unit controls to inject a certain amount of sample and a certain amount of dilution solution, and the content of the sample is measured after the sample is diluted. No matter which method is adopted, unreasonable dilution and poor accuracy can be caused, and the unattended requirement of the analyzer can not be met.
