Problems solved by technology

[0004] However, the process of analyzing and testing method experiments on the existing LIBS experimental platform is often too cumbersome
These experimental platforms are assembled from components from different manufacturers. Each component (such as a laser) is controlled by an independent operating software. Operators need to frequently switch between different software to complete the control of the entire experimental platform. The integration of the entire experimental platform is relatively low. Low; during the experiment, when it is necessary to test the influence of a parameter gradually changing within a fixed range on the test results, the operator needs to continuously modify the parameter value to conduct experiments until all values ​​are traversed, and the automation of the entire experiment process is low
The integration and low automation of the experimental platform have brought great complexity to the research of analytical methods and reduced the efficiency of analytical method research
