Organic and Biochemical Material


Different biomaterials were prepared as thin sections (up to 20 Μm thick, 8 mm in diameter) by means of a freezing microtome on a quartz-glass carrier and analyzed directly by total-reflection X-ray fluorescence (TXRF). They were originally available either as compact samples, as powder material or as solutions. About 20 elements with atomic numbers between 15 and 40 (P and Zr) and between 57 and 92 (La and U) were determined simultaneously with detection limits of some Μg/g. — The method was applied to the analysis of plant and animal foodstuff (nuts, mushrooms, shrimps) and of different organic tissue (human lung). The TXRF-spectra, like fingerprints, facilitate the easy characterization of samples and turn out to be very suitable for screening and monitoring tasks.
