METHOD 3052
MICROWAVE ASSISTED ACID DIGESTION OF SILICEOUS AND
ORGANICALLY BASED MATRICES
1.0 SCOPE AND APPLICATION
1.1 This method is applicable to the microwave assisted acid digestion of siliceous
matrices, and organic matrices and other complex matrices. If a total decomposition analysis
(relative to the target analyte list) is required, the following matrices can be digested: ashes,
biological tissues, oils, oil contaminated soils, sediments, sludges, and soils. This method is
applicable for the following elements:
Aluminum Cadmium Iron Molybdenum Sodium
Antimony Calcium Lead Nickel Strontium
Arsenic Chromium Magnesium Potassium Thallium
Boron Cobalt Manganese Selenium Vanadium
Barium Copper Mercury Silver Zinc
