Comparison of Handheld and Echelle Spectrometer to Assess Copper in Ores by Means of Laser-Induced Breakdown Spectroscopy (LIBS)

Laser Induced Breakdown Spectroscopy (LIBS)

Analysis by laser-induced breakdown spectroscopy of complex solids, liquids, and powders with an echelle spectrometer.

One of the most promising approaches to laser-induced breakdown spectroscopy (LIBS) experiments involves the use of an echelle spectrometer coupled with an intensified CCD. Even if drawbacks remain with its use, the echelle spectrometer facilitates a multielemental analysis that is more rapid than can be obtained with the more-conventional Czerny-Turner spectrometer and, moreover, does not sacr...

Remote Laser - induced Breakdown Spectroscopy ( LIBS ) Analysis of Hydrated Sulfates

Introduction: One of the most promising of instruments selected for the upcoming Mars Science Laboratory (MSL) mission for analyzing Martian rocks is the remote Laser-Induced Breakdown Spec-troscopy (LIBS) on the ChemCam instrument package. The LIBS technique involves focusing a laser pulse beam at a distant target with sufficiently high energy that a plasma is made, reducing a small spot on th...

Measuring total soil carbon with laser-induced breakdown spectroscopy (LIBS).

Improving estimates of carbon inventories in soils is currently hindered by lack of a rapid analysis method for total soil carbon. A rapid, accurate, and precise method that could be used in the field would be a significant benefit to researchers investigating carbon cycling in soils and dynamics of soil carbon in global change processes. We tested a new analysis method for predicting total soi...
