Solid or liquid samples are weighed and introduced into the sample boat. The sample is initially dried and then thermally decomposed in a continuous flow of oxygen. Combustion products are carried off and further decomposed in a hot catalyst bed. Mercury vapors are trapped on a gold amalgamator and subsequently desorbed for quantization.
The mercury content is determined using atomic absorption spectrophotometry at 254 nm.
