Abstract

Laser-induced breakdown spectroscopy (LIBS) has numerous advantages like determination of ppb-ppm level concentrations, microdestructivity, the ability of making high resolution laterally (µm) or depth-resolved (100 nm) analysis, sensitive measurement of heavy and light elements and direct analysis of solid samples with minimal sample preparation. The aim of the present work was to demonstrate that LIBS is a suitable analytical technique to assess the trace element distribution of pharmaceutical and biological samples. As test samples, we used specimens of chickpea milkvetch (Astragalus cicer), a perennial plant with excellent nutritional value and a commercially available dietary supplement pill (Supradyn).
