A major news in the field of analysis this century is that NASA has adopted LIBS technology as a mineral analysis tool for the surface of Mars rovers - ChemCam, and has successfully completed scientific research missions. Therefore, the application of LIBS technology has also become a major research hotspot. Compared with other commonly used methods of elemental analysis, its main advantages are:

(1) By utilizing the unique performance of lasers, remote, real-time, and online element detection can be achieved.

(2) The instrument has a relatively small volume, suitable for on-site analysis and can be used for measurements under harsh conditions.

(3) It can be used for the analysis of various forms of solids, liquids, and even gases, without the need for tedious sample pretreatment processes, making the analysis simple and fast.

(4) It can measure high hardness materials that are difficult to dissolve, with no strict requirements for sample size and minimal damage to the sample, achieving micro damage or even close to non-destructive testing. The sample consumption is extremely low (about 0.1 μ g-0.1mg).

(5) The analysis time is short, and the entire process from laser pulse emission to signal collection only takes milliseconds.

(6) Multiple elements can be detected simultaneously.
