Measuring principle<\/strong><\/span><\/p>\n

Mercury is measured after total digestion. Ionic mercury in acidic solution is then reduced by a reducing agent producing ground state atomic mercury. After equilibration, the mercury vapor is swept from the reaction vessel by passing the sample through an efficient gas \/ liquid separator and purging with high purity argon gas. The Hg is transferred into an inert gas stream that brings the liberated Hg (0) into the chamber of a cold-vapor atomic fluorescence spectrometer (CVAFS) for detection. The concentration of Hg is determined by atomic fluorescence spectrometry at 253.7 nm. Quality is guaranteed through calibration and assessment of the oxidation, purging, and detection systems. No interference from transition metals (Fe2+<\/sup>, Fe3+<\/sup>, Zn2+<\/sup>, Cu2+<\/sup>, Ni2+<\/sup>, Pb and Cr3+<\/sup>) and hydride-forming elements (Se4+<\/sup>, Sb3+<\/sup> and As3+<\/sup>) is observed.<\/p>\n

Product features <\/strong><\/span><\/p>\n

Extended mean time between refilling \/ emptying \/ replacing operations<\/strong>: the unattended running time is improved by the presence of a gas-saving device and the storage at low-temperature of the reducing agent. Mean time between maintenance activities is effectively extended by the dual lamp position design, through the light source switching.<\/p>\n

Accurate results<\/strong>: adopting the recommended international standard method-based on cold vapor atomic fluorescence, the detection results are highly compatible with the laboratory method.<\/p>\n

Extremely low detection limit<\/strong>: the indirect method using the cold vapor technique allows mercury to be detected very sensitively with minimal background. The superior signal-tonoise ratio of the atomic fluorescence method allows for detection and quantitation limits in the sub \u03bcg \/ L range.<\/p>\n

High adaptability<\/strong>: built-in automated digestion module, the analyzer is high adaptable to a wide range of water samples, characterized by different water quality.<\/p>\n
