Nowadays, after three decades of technological development, it is clear that microwave-assisted sample preparation is not just fast heating, but also brings new strategies fully compatible with modern trace analysis. This statement is crystal clear when working with ultraCLAVE and ultraWAVE instruments. Based on the Single Reaction Chamber (SRC) technology, these instruments allow reaching pressures of up to 199 bar and temperatures as high as 300° C depending on the reaction vessel.
It is well known that mercury and its multiple forms are critical contaminants to the environment with severe consequences for food chain and humans. The determination of trace levels of Hg is a must and frequently measurements are performed by converting Hg to a vapor and measuring its concentration either by atomic absorption or by atomic fluorescence.
