Multifunctional mercury spectrometer

Due to the low power consumption (15 W) and low weight (16 Lb. with built-in batteries) the spectrometer can be used for mercury determination in air and natural gas, samples of soils, rocks, water in laboratory as well as in field conditions.

MERCURY DISTRIBUTION IN AIRMERCURY DISTRIBUTION IN AIR

MERCURY DETERMINATIONMERCURY DETERMINATION

Mercury distribution along the profile crossing the area of an unidentified ore mine and a smelter.

M –mineC – central part of mineS – smelterW – waste dump

Figure shows the results of mercury determination along the profile of a mine, smelter and a waste dump. The RA-915+ analyzer was placed in a car, and ambient air was continuously pumped through the instrument at a rate of 20 l/min. As can be seen, with the speed of the car at about 35mph, two high peaks were detected in the central part near the mine, smelter, and dumps.
