Ensuring drinking water resources meet regulatory requirements and are safe for human consumption requires the testing for a wide range of possible contaminants. Using approved analytical methods, scientists in municipal water facilities and contract labs routinely monitor for pollutants such as inorganic anions and cations, metals, radionuclides and organic contaminants using a range of PerkinElmer solutions including ICP-OES, ICP-MS, GC, GC-MS, LC, LC-MS and others. These solutions provide reliable, robust, sensitive, and efficient results that allow water quality professionals to protect human health.
