The method relies on . Unlike traditional absorption methods, CVAFS measures the light emitted by excited mercury atoms.

: High-purity argon gas carries the vapor into the CVAFS analyzer , where it is exposed to UV light (253.7 nm), causing fluorescence that is then measured. Critical Interferences 245.7z.001

: Samples are first treated with a brominating digestion (potassium bromate/bromide) to convert all mercury forms into mercuric ions ( Hg2+cap H g raised to the 2 plus power The method relies on
