Laser-Induced Breakdown Spectroscopy Beyond the Lab

Facebook X LinkedIn Email
Offering advantages over other analytical techniques, laser-induced breakdown spectroscopy is useful in mineral extraction, forensics and point-of-care blood analysis.

BENNO ODERKERK AND JANEL KANE, AVANTES

Laser-induced breakdown spectroscopy (LIBS) techniques have been studied and applied for more than half a century. The first plasma induced by a laser was observed shortly after the invention of the laser itself, but only recently has LIBS moved from research circles to industry. Here’s how the technique works: A laser pulse instantly heats a small volume of matter to several thousand degrees when focused on a surface for a few nanoseconds. As it cools, this laser-heated matter returns the absorbed energy through visible and invisible portions of the spectrum. Light emission is...Read full article
