Abstract:
     The present invention relates to mercury vapour measurement instrument for geochemistry prospect and environmental protection. Said invention adopts microprocessor to control whole course of measuring to make the measurement condition strictly consistent and measurement course automatization. It adopts also a micro mercury capture tube fixed on inside of instrument to lower the electric consumption is instrument, thus making the overall electric consumption can be supplied by a battery group, and making all the size, weight and power consumption meet the requirements of field measurement comparing with the available atomic absorption mercury measuring instrument, the detecting limit of said instrument increases by one order of magnitude. Said instrument features no saturation phonomenon, higher measuring accuracy and suitable for super micro measuring of mercury.
