An innovative method for materials analysis called LIBS is developing quickly and is starting to be recognized as a crucial instrument in analytical chemistry. LIBS technology is also progressing in various aspects. Because LIBS is inherently versatile, it can be used elegantly in different circumstances. However, to get accurate results, it's necessary to be aware of this method's analytical constraints before development, the validation must be done depending upon the critical needs. Discovering and identifying rocks and minerals; using resources; slurry and drill cores; rare earth elements; and light elements. LIBS is crucial in geology, biomedical, microbial, drug elemental, and pharmaceutical analysis. LIBS was first introduced in 1962 by Townes.
