Laser-induced breakdown spectroscopy (LIBS) is an atomic emission spectroscopy technique that uses a short laser pulse to create a micro-plasma on a sample surface. It is used for the rapid chemical analysis of materials in a host of industrial applications. This white paper introduces a very compact, air-cooled, pulsed laser and demonstrates how it can be effectively used in conventional LIBS experimental set-ups for identifying metals.
Spectroscopy plays a key role in the future of agriculture. In this white paper, Avantes shows you how this technology helps the market work smarter and more efficiently.
