Scope

1.1 This method is applicable to the microwave assisted acid digestion of siliceoi matrices, and organic matrices and other complex matrices. If a total decomposition analys (relative to the target analyte list) is required, the following matrices can be digested: ashe biological tissues, oils, oil contaminated soils, sediments, sludges, and soils. This method applicable for the following elements: Aluminum Antimony Arsenic Boron Barium Beryllium Cadmium Calcium Chromium Cobalt Copper Iron Lead Magnesium Manganese Mercury Molybdenum Nickel Potassium Selenium Silver Sodium Strontium Thallium Vanadium Zinc Other elements and matrices may be analyzed by this method if performance is demonstrated f( the analyte of interest, in the matrices of interest, at the concentration levels of interest (see Sei 8.0). Note: This technique is not appropriate for regulatory applications that require the use < leachate preparations (i.e., Method 3050, Method 3051, Method 1311, Method 1312, Metho 1310, Method 1320, Method 1330, Method 3031, Method 3040). This method is appropriat for those applications requiring a total decomposition for research purposes (i.e., geologic; studies, mass balances, analysis of Standard Reference Materials) or in response to regulation that requires total sample decomposition. 1.2 This method is provided as a rapid multi-element, microwave assisted acid digestio prior to analysis protocol so that decisions can be made about the site or material. Digests an alternative procedures produced by the method are suitable for analysis by flame atomic absorptio spectrometry (FLAA), cold vapor atomic absorption spectrometry (CVAA), graphite furnace atomi absorption spectrometry (GFAA), inductively coupled plasma atomic emission spectrometry (ICF AES), inductively coupled plasma mass spectrometry (ICP-MS) and other analytical elements analysis techniques where applicable. Due to the rapid advances in microwave technology, consu your manufacturer's recommended instructions for guidance on their microwave digestion systen and refer to this manual's "Disclaimer" when conducting analyses using Method 3052. 1.3 The goal of this method is total sample decomposition and with judicious choice c acid combinations this is achievable for most matrices (see Sec. 3.2). Selection of reagents whici give the highest recoveries for the target analytes is considered the optimum method condition.
