ICP-MS is widely used for the multielement analysis of trace metals in drinking waters. The newly designed 7800 ICP-MS accurately measured drinking waters for all required elements at regulated levels, without the need for either reactive cell gases or complex interference equations. Using helium collision mode, selenium detection limits less than 20 parts per trillion (ppt) are now routinely achievable.
