The ability to perform an in-situ analysis is often a key precondition for testing the LIBS as a tool for real-world applications. Principles of the LIBS enable the use of this technique out-of the lab. We have designed and built a mobile LIBS laboratory – the computer controlled modular device that is equipped with the laboratory-grade instrumentation and that is able to perform LIBS analysis in-situ remotely at a distance of up to and over 20 m.
