Abstract

This work is focused on application of LIBS technique for the study of plant samples. The elemental mapping on cross section throughout the annual terminal twigs of Picea abies was performed using double pulse Laser Induced Breakdown Spectroscopy (DP LIBS). 2D maps were created, where distribution of Cu and Ca in the plant tissue was observed. After mineralization of twig parts originated in the vicinity of the implementation of cross section, ICP-MS analysis was used for determination of total content of investigated elements.

Abstract

Single pulse (SP) LIBS setup was modified to DP setup to achieve more accurate analytical sensitivity and spatial resolution. All parameters, like interpulse delay, acquisition delay or energy of ablation and excitation laser pulses were optimized.

Abstract

Bio-mineral structures, i.e., bones, teeth or kidney stones have been found to be excellent ""archives"" related to nutrition, living habits and exposure to changing environmental conditions. More specifically, formation of urolithic concrements (uroliths) represents specific biomineralization of living organism. Line scans of the concrement cross sections may provide information about the accumulation history of the elements of interest. Analytical Methods which can map the presence of different elements are e.g. Laser Induced Breakdown Spectroscopy (LIBS) and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). Both of these methods have proven to be suitable for mapping the matrix elements, so further work is concerned with their use for the mapping of trace elements.
