A direct mercury analyser Milestone DMA-80 was used for
direct determination of Hg in untreated and fat-free samples by
atomic absorption after sample ashing and Hg pre-concentration
in a gold trap. The instrument was equipped with an auto sampler
with a capacity of forty sample boats, an interference
filter of
254 nm with 9 nm width and a silicon detector which measured
the absorbance signal of Hg at 253.6 nm
