: 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
This method is performance-based, meaning laboratories can use different equipment, such as the PSA Millennium Merlin or Teledyne QuickTrace , provided they meet strict quality control standards. It typically operates within a calibration range of 5 ng/L to 100 ng/L.
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:
: Stannous chloride is added to reduce these ions into elemental mercury vapor ( Hg0cap H g to the 0 power : Samples are first treated with a brominating
: Gold, silver, and iodide can interfere with the reduction process.
The method relies on . Unlike traditional absorption methods, CVAFS measures the light emitted by excited mercury atoms. Below is a structured overview (essay) of this
