introduction: a modern technique for elemental analysis of biological samples is laser induced breakdown spectroscopy (libs). this technique is based on emission of excited atoms, ions, and molecules in plasma produced by focusing a high power laser pulses on sample surface. because of several advantages of libs including little or no sample preparation; minimally invasive; fast analysis time a...

Laser-induced breakdown spectroscopy (LIBS) is an ideal method for elemental analysis of geological samples. Although X-ray fluorescence (XRF) can measure a wide variety elements, it struggles to elements lighter than silicon, meaning that many key crustal cannot be measured. In addition, as fast, standoff method, LIBS employed in geometries with various distances from the target. has famously ...

The huge consumption of modern plastic with improper disposals has posed a great threat to the environment and human beings. To put these post-consumer plastics into recycling chain, laser induced breakdown spectroscopy (LIBS) been established as potential tool for rapid grading online. Meanwhile, LIBS is powerful investigations in laboratory capacity simultaneous qualitative quantitative analy...
