MERCURY BY COLD VAPOUR ATOMIC ABSORPTION SPECTROSCOPY (CV-AAS)
P S Analytical analysers generally utilise Atomic Fluorescence Spectroscopy (AFS) which offers many advantages over techniques for the determination of mercury and the hydride forming elements including better sensitivity, selectivity and linearity.
