Please contact us for assistance. In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Jump to main content.
The accuracy of these methods depends on precise replication of the reaction conditions. Apart from hot-plate based open vessel digestion ea, EPA also specifies closed-vessel microwave-assisted sample preparation procedures for the analysis of up to 26 elements. Since this method is not intended to accomplish total decomposition of the sample, the extracted analyte concentrations may not reflect the total content in the sample.

Due to a lapse in appropriations, EPA websites will not be regularly updated. After cooling, the vessel contents are filtered, centrifuged, or allowed to settle and then diluted to volume and analyzed by the appropriate determinative method. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.
