2 Cadmium determination with the graphite tube technique (Furnace method) 

Optimum measuring range Determination limit Calibration Acid concentration 

10 ml nitric acid (1.40 g/ml) per 1000 ml sample solution 10 pi 0.1 % ammonium dihydrogen- 

It is advisable to use a so-called platform. Decomposition with sulphuric acid/nitric acid is required for water samples which contain more than 10 mg/1 of organically bonded carbon.
