Example Embodiment

[0038] Example 1

[0039] This embodiment is used to illustrate the nanoparticle size concentration detection system of the present invention.

[0040] The nano particle size concentration detection system of the present invention mainly includes a sample collection, a cleaning system and a detection chip.

[0041] The sample collection and cleaning system consists of figure 1 As shown, the sample collection tube 1' is installed on the sample detection sensor. When the sample sensor detects the sample, the sample collection mechanical arm movement module 6 moves the sample collection tube 1' to the top of the sample collection tube 2, and the sample flows into the sample collection tube 2. Among them, the inlet of the peristaltic pump 14 is connected to the sample collection tube 5 through a conduit, the outlet 8 of the peristaltic pump is connected to the multi-channel valve 13, and the multi-channel valve 13 is respectively connected to the chip inlet 11 of the detection ...

Abstract

The invention provides a nano-particle size concentration detection system. The system comprises a sample collecting and cleaning system, a detection chip and a laser, wherein the sample collecting and cleaning system is connected with the detection chip to control the flow of a sample and a cleaning solution in the detection chip. The detection system disclosed by the invention can derive the particle size and concentration of the nanoparticles by observing the motion trail and number of the nanoparticles in a solution state, so the nanoparticles can be ensured to be in an original state, and the result is accurate and reliable. The system can be used as a module to be combined with a nano-particle synthesis system, so man-made interference caused by separated experiments is reduced. The system disclosed by the invention is simple and convenient to operate and has the characteristic of high throughput.

Description

technical field [0001] The invention belongs to the field of nanometer technology, and in particular relates to a nanoparticle size concentration detection system and a detection method thereof. Background technique [0002] Nanoparticles are widely used in electronic information, biomedicine, chemical industry, aerospace and other fields. Since the microstructure of nanoparticles, such as particle size and shape, has an important relationship with their characteristics, the characterization of the microstructure of nanomaterials is very important for promoting the development of nanomaterials. It is extremely important, and the size and concentration measurement of nanoparticles is one of the key technologies. [0003] Currently, methods for measuring the size of nanoparticles include dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), atomic force microscopy (AFM), and transmission electron microscopy (TEM). Among them, NTA collects the scattered light s...
