EPA 245.7 Mercury by ICP-MS Laboratory Testing Service: A Comprehensive Guide
Standard-Related Information
The European Unions environmental regulations, particularly the EU Water Framework Directive (2000/60/EC), emphasize the need for accurate and reliable measurements of mercury in water samples. The US Environmental Protection Agencys (EPA) Method 245.7, Mercury in Water by Cold Vapor Atomic Absorption Spectrometry (CVAAS), is widely accepted as a standard method for determining mercury concentrations in water. However, with the increasing popularity of Inductively Coupled Plasma Mass Spectrometry (ICP-MS) technology, the EPA has published Method 245.7A, which uses ICP-MS instead of CVAAS.
