DIRECT DETERMINATION OF MANGANESE IN MICROGRAM AMOUNTS OF PANCREATIC TISSUE BY ELECTROTHERMAL ATOMIC-ABSORPTION SPECTROMETRY
Manganese is determined by the direct insertion of freeze-dried biological samples (1-15 μg) or by injection of 2-μl samples of perifusion medium into the graphite furnace. At the most sensitive wavelength (279.5 nm), down to 0.2 pmol of manganese can be measured in the perifusion medium as well as...
