Design method of portable device for measuring concentration of sol solution based on Tyndall effect

Abstract

The invention discloses a design method of a portable experimental device for measuring the concentration of a sol solution based on a Tyndall effect. The device comprises a rotatable sample mountingand rotating part, a mounting bottom plate, a light source part, an image sensor part, a spring positioning part, an upper cover plate, a side cover plate and the like. Wherein the sample mounting androtating part is composed of a test tube mounting disc, a test tube bottom supporting disc, a rotating shaft and the like; the light source is installed on the light source fixing support, the digital image sensor is installed on the sensor fixing support, and the light source fixing support and the sensor fixing support can be adjusted in position in the light source installation adjusting groove of the installation bottom plate and are fixed through threads. The spring positioning bead is installed on the positioning bead fixing support, and the positioning bead fixing support is installedon the installation bottom plate. The device is simple in structure, convenient to operate, low in manufacturing cost, convenient to carry and suitable for field analysis and timely measurement.

Description

technical field [0001] The invention relates to a portable measuring device for measuring the concentration of a sol solution based on the Tyndall effect, which is mainly used for measuring the concentration of a sol solution containing nano-gold, nano-silver ions and the like in the field. Background technique [0002] Quantitatively measuring the concentration of liquids has a wide range of demands in various fields. At present, liquid concentration detection methods mainly include chemical titration, spectroscopy, spectrophotometry, optical rotation, resonance method, and fluorescent probe method. These methods and related detection instruments have the advantages of mature technology and high detection accuracy, but these instruments The device has disadvantages such as high price, large volume, and high requirements for environmental conditions. It needs to be used in the laboratory, and cannot meet the needs of carrying and testing liquid immediately after sampling in ...

AI Technical Summary

Problems solved by technology

At present, liquid concentration detection methods mainly include chemical titration, spectroscopy, spectrophotometry, optical rotation, resonance method, and fluorescent probe method. These methods and related detection instruments have the advantages of mature technology and high detection accuracy, but these instruments The device has disadvantages such as high price, large volume, and high requirements for environmental conditions. It needs to be used in the laboratory, and cannot meet the needs of carrying and testing liquid immediately after sampling in the field.

In some current special applications, it is necessary to sample the researched liquid object in the field and immediately detect the concentration of the sampled liquid. The previous liquid concentration detection methods and devices are difficult to meet this requirement
