For the analysis of heavy metals in wastewater, the methods of the US Environmental Protection Agency (EPA) are considered reference for analysis worldwide. The US EPA published Method 6020B to control 23 metals in environmental water using ICP-MS. ICP-MS can analyze many elements at the ppt levels and allows for simultaneous analysis by directly introducing wastewater samples.
In this Application News, 23 elements in wastewater were analyzed using the ICPMS-2050. Analytical samples’ spike recovery tests and long-term stability tests were performed in accordance with the quality control (QC) requirements of the EPA Method 6020B.
