A home – made purge and trap – thermos desorption - gas chromatograph coupled with atomic fluorescence detector for the determination of ultra – trace methylmercury
The trap was then heated to release volatile compounds including ethylmethylmercury into a GC-AFS for separation and detection. The instrumental detection limit was 4.8 pg Hg/L. The method can therefore be applied for the determination of methylmercury in water samples at ultra – trace.
