Microwave-laser mixing plasma detection system

Abstract

The invention discloses a microwave-laser mixing plasma detection system which combines microwave and laser plasma stimulating and detecting technologies. The microwave-laser mixing plasma detection system is a system which can independently complete detection of element and substance component contents. The detection system mainly comprises a light source module, a microwave module, a sample module, a control module, a detection module, a logic module and a display module, wherein the logic module is connected with the control module, the detection module and the display module; the control module controls the light source module, the microwave module and the detection module; the microwave module emits microwaves to stimulate plasmas, and then the light source module carries out secondary plasma stimulation; in the whole process, the microwave module continuously outputs the microwaves to prolong the life of the plasmas; the detection module transmits information to the logic module; after being processed, the information is displayed on the display module. The microwave-laser mixing plasma detection system is higher in detection precision and lower in detection lower limit, and a detected sample does not need to be preprocessed.

Description

technical field [0001] The invention belongs to a detection system, and in particular relates to a detection system which enhances plasma detection through microwave laser mixing. Background technique [0002] Plasma detection, which is a kind of spectral detection technology that has gradually emerged in recent years by measuring the induced plasma spectrum on the surface of a substance, is a kind of atomic emission spectroscopy. Plasma technology is so far the only known technique capable of detecting spectra of all elements in any environment; also in various sample forms in solid, liquid, powder, gas form. At the same time, the plasma detection technology has many advantages such as fast measurement speed, remote non-contact measurement, and simple system structure. Based on the many advantages and versatility of plasma detection technology, some people call it a "universal" detection technology. [0003] At the same time, it cannot analyze multiple elements at the sam...

Problems solved by technology

[0004] However, there are certain problems in traditional plasma detection, for example, the detection limit is not low enough, resulting in the minimum detection limit of many elements being higher than the national standard value, which makes it more difficult for the comprehensive promotion of plasma detection to food safety and environmental detection
