Laser-Induced Breakdown Spectroscopy in the Physical Sciences

Posted on: August 20th, 2019

LIBS in the Physical Sciences app note 190515 Laser-Induced Breakdown Spectroscopy employs a laser to ablate the surface of a sample which creates a small plume of plasma. Using a form of atomic emission spectroscopy, the light of this plasma is captured and analyzed for quantitative and qualitative atomic properties. As the popularity of this…

Spectroscopy Plays a Key Role in the Future of Smart Agriculture

Posted on: May 23rd, 2019

The future of agriculture will be shaped by technological advances as much as by the forces of climate change and population growth. This means that the farms of the future will need to produce more with less space, fewer resources, and often in ever-worsening conditions. The technological advances that will shape the future of agriculture…
