摘要：

Pressure digestion units made from stainless steel, with up to 12 sample positions, are described. The sizes of the teflon digestion crucibles are 0.6 resp. 35 ml for sample weights (dry weights) from about 10 up to 1000 mg. The handling of the units and the digestion crucibles, the standard digestion program with nitric acid (needed time including cooling period about 3 h), its evaluation and the very important safety aspects are extensively discussed. © 1978 Springer-Verlag.
