Through the NIES (National Institute for Environmental Studies) CRM (certified reference material), it has been required to investigate and develop a contamination-free digestion system for biological materials, since trace element levels in these matrices are so low that contamination during sample dissolution procedure often became a limiting factor for trace analysis. At an earlier stage, a Teflon bomb developed by Iida et al. was used for the decomposition of NIES Chlorella and Freeze-Dried Serum reference materials. Recently, an improved Teflon bomb method has been developed. The method uses a small screw cap vial for sample decomposition inside the Teflon digestion vessel. This digestion system can reduce the risk of sample leakage and contamination with extraneous materials and can be applied to biological materials up to approximately 300 mg of dry weight. 7 references, 1 figure, 1 table.
