The accuracy of these methods depends on precise replication of the reaction conditions. Due to a lapse in appropriations, EPA websites will not be regularly updated.

This document explains the procedure designed to mimic extraction using conventional heating with nitric acid HNO3or alternatively, nitric acid and hydrochloric acid HCl. Please contact the webmaster here. You may need a PDF reader to view some of the files on this page.
We’ve made some changes to EPA. This microwave extraction method is designed to mimic extraction using conventional heating with nitric acid HNO3or alternatively, nitric acid eppa hydrochloric acid HClaccording to EPA Method While A and A are acid 3051z methods, is flexibly adaptable for total digestion.
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. Generally the aim of such methods is to improve analytical performance and reliability.

In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect 3051q property, the EPA website will be updated with appropriate information. 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.
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.
These EPA methods do not depend on the used instrument, as they prescribe temperature profiles 3051x of instrument-specific power programs. The test methods page continues to expand and improve. After cooling, the vessel contents are filtered, centrifuged, or allowed to settle and then diluted to volume and analyzed by the appropriate determinative method.
