This is an automated instrument for analysing methylmercury (MeHg), the most toxic organic form of Hg, in environmental samples. It is a purge and trap system based on gas chromatography (GC) separation and cold vapour atomic fluorescence spectrometry (CV AFS) detection, and is extremely sensitive (even < 0.002 ng/L for 40 ml samples). It complies with EPA method 1630, used for the determination of MeHg in water, sediments, biological tissues, etc.
