Abstract
A semiconductor low-temperature elemental mercury generator is provided, and includes a gas source and a mercury pool generating chamber, the gas source is communicated with a carrier gas pipeline and a dilution gas pipeline. The mercury pool generating chamber includes a semiconductor refrigeration device, a gas mixing device and a coil, the coil is kept at a constant temperature through the semiconductor refrigeration device, the carrier gas pipeline is communicated with the coil, and the gas mixing device is communicated with a gas outlet of the coil and the dilution gas pipeline. The semiconductor low-temperature elemental mercury generator has the advantages of simple operation and accurate mercury standard gas concentration.
