Summary of Method This method is based on the absorption of radiation by mercury vapor at the 253.7nm line. The mercury is first reduced to the elemental state using the procedure outlined in EPA method 245.1. Air is then bubbled through the sample, speeding the mercury vapor to the absorption cell. The 253.7nm mercury line emitted by the lamp is absorbed by the vapor in the cell in proportion to the mercury concentration. The Digital readout result is transmitted to the Digital readout which can be read directly in concentration of mercury. The instrument has a built-in “Peak-Picker” which...
