Chemical Analysis of Zooplankton by Calibration-Free Laser-Induced Breakdown Spectroscopy

Catching up on calibration-free LIBS

“…Hafeez et al 67 explored, using CF-LIBS, the possible presence of precious elements in a copper-rich mineral (malachite) and conrmed the results obtained by X-ray uorescence. Sushkov et al 68 determined by CF-LIBS the Li, Mg, and Ca ratios in zooplankton and conrmed the results with ICP-MS.…”

A novel approach for discovering correlations between elemental and molecular composition using laser-based spectroscopic techniques

“…Since the accumulation through the food chain and passive sorption are considered unlikely, there should be a physiological mechanism for its active accumulation, as well as a certain biological function which is yet to be clarified. [2][3][4][5] It is therefore interesting to find correlations between compositional features of copepod tissues to provide insight into reasons behind lithium accumulation. To this end, fast, informative and virtually non-destructive techniques 6 like laserinduced breakdown spectroscopy (LIBS) and Raman spectroscopy come into question.…”
