Apart from hot-plate based open vessel digestion methods, EPA also specifies closed-vessel microwave-assisted sample preparation procedures for the analysis of up to 26 elements. If you have suggestions for improvement, we would enjoy hearing from you.
We’ve made some changes to EPA. After cooling, ep vessel contents are filtered, centrifuged, or allowed to settle and then diluted to volume and analyzed by the appropriate determinative method.
