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

However, based on the specific number , this often refers to EPA Method 245.7 , a high-precision protocol for measuring mercury levels in water. Below is a structured overview (essay) of this technical method. Overview of EPA Method 245.7: Mercury Detection 245.7z.001

To maintain accuracy, analysts must manage several chemical interferences: The method relies on

: 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 based on the specific number
