DMA-80

 

 

 

 

Solid, liquid or gas 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.
