Abstract

Mercury is an element causing harm to environment and that is why analyzing mercury always takes interest and concern. Detecting trace of mercury in minor concentration is carried out by technique of mercury cold vapor system. Using circulation mode in analyzing, we can determine approximately 0,1 ppb mercury in water. The detection limit can be improved to 0,01 ppb by taking advantage of suction mode and using T absorption cell instead of the ordinary cell equipped MVU-1A.
