Abstract

The invention discloses a novel cuvette for water quality on-line monitoring equipment, which relates to the field of water quality on-line detection and comprises a cuvette main body, and a frosted layer is arranged on the outer side of the cuvette main body. Through the design of the cuboid cuvette, the contact surface of incident light and the cuvette can be ensured to be a plane, and the difficulty of vertical irradiation of specific color light and the refraction error of the incident light are greatly reduced; a ceramic heating sheet is arranged at the bottom to heat the liquid, so thatthe heating uniformity of liquid digestion can be improved; by setting the width and the depth of the inner cavity of the cuvette, on the premise of realizing small sample size, large-optical-path colorimetric detection can be obtained, and secondary pollution of a reagent is reduced while the precision is improved; a slope is designed in an inner cavity of the cuvette, so that liquid emptying isfacilitated; and the sample inlet is connected with the side wall of the inner cavity, and the temperature sensor mounting hole is moved to the bottom, so that cleaning dead angles can be eliminated,and the cuvette cleaning effect is improved.

Description

technical field [0001] The invention relates to the field of online water quality monitoring, in particular to a novel cuvette used for water quality online monitoring equipment. Background technique [0002] The structure of water quality online monitoring equipment is determined by the detection method it adopts. There are many methods for water quality detection, among which spectrophotometry is the most widely used. Spectrophotometry is a method based on Lambert-Beer law. The developed water quality detection method has the advantages of good selectivity, high sensitivity, low analysis cost, simple and easy to implement equipment, etc., and has realized the determination of most water quality detection factors, and has become a standard method for the detection of various water quality factors. When the water quality automatic analyzer based on spectrophotometry detects water quality factors, if the concentration of water quality factors is too low, the sensitivity of th...
