Improvements in the determination of mercury by cold-vapor atomic absorption spectrometry

cited By 13International audienceSeveral improvements to a conventional mercury analyzer system are described. The type of system, the shaking and reduction efficiency, the geometry of the absorption cell, the gas flow and the volume of the reduction vessel are modified. The detection limit is then 0.25 ng of mercury. The results emphasize the role of gas flow dynamics in the circuit. © 1983
