Apparatus for total mercury analysis
Reductive volatilizing apparatus Stannous ion (Sn2+) reduces mercuric ion(Hg2+) to mercury vapor (Hg0)	Heating at 800℃ for several minutes Changes mercuric ion (Hg2+) to mercury vapor(Hg0)	Amount of mercury This figure shows analytical result of mercuric chloride standard sample. One milligram of hair sample containing 1 ppm mercury gives a peak corresponding to 1 ng.
Apparatus for methylmercury analysis
Apparatus for methylmercury analysis This figure shows data of methylmercuric chloride standard solution. Sensitivity is higher than total mercury analysis.
