HG-400

The HG The HG- -400/450 400/450 is a low cost mercury analyzer that has been especially designed for the environmental analyses in the budget-conscious small and medium size laboratory. This analyzer is based on cold vapor atomic absorption spectroscopy (CVAAS) using the principals of reduced vaporization. As such, it does not require any compressed gases and offers detection limits considerably below than 1ppt. The unit is a dedicated mercury analyzer and does not require any expensive additions or optional equipment. The dry air delivery system and the charcoal filter trap require very little maintenance �while providing detection limits down to 0.5ppt in a 5-mL sample.
