Abstract
Blank values of 30 elements in 19 different filter types from Gelman, Millipore, Nuclepore and Whatman have been compared. The filter media were extracted with dilute nitric acid and the element contents determ ined by ICP-MS. Large differences in blank values were observed betwee n different filter materials. Glass fiber filters showed high blank va lues for a number of elements, whereas PTFE filters were generally the cleanest. However, most filter types showed high blank values of one or more elements of environmental interest.
