MERCURY MONITOR

摘要

The claimed invention refers to analytical systems of automatic measurement of mercury concentration and can be used to monitor industrial and sewage water and combustion gases. The task of the proposed invention is improvement of consumer characteristics of the monitor, increase in unattended operating time of the monitor and ensuring long functioning of the monitor. The set task is achieved by the mercury monitor including the input sample unit, the thermal atomizer, the analytical cell capable of being heated, the gas collector unit, and the sucking out pump, at that the analytical cell contains two windows being? transparent for resonant radiation of mercury, through one of which (at least) it is optically coupled with the atomic-absorption spectrometer; at least, one input gas port is located in its central part and, at least, two output gas ports, each of which is located between input gas port and the corresponding window, wherein the sample input unit is coupled with injecting pump capable of introducing the sample analyzed into the thermal atomizer, and the analytical cell has openings located in its both ends between the window and the nearest output gas port through which possibility of gas supply is realized.
