Descriptions of each method
Method 200-2
This method provides sample preparation procedures for the determination of total recoverable analytes in groundwaters, surface waters, drinking waters, wastewaters, and, with the exception of silica, in solid type samples such as sediments, sludges and soils.
Method 200-7
This method is used to determine concentrations of trace elements in water, solids, and Biosolids by Inductively coupled plasma-atomic emission spectrometry.
Method 200-9
This method is used to determine Trace Elements in Water, Solids, and Biosolids by Stabilized Temperature Graphite Furnace Atomic Absorption Spectrometry.
Method 1685
This method is used to determine Nitrate/Nitrite-N in Water and Biosolids by Automated Photometry.
Method 1686
This method is used to determine Nitrate/Nitrite-N in Water and Biosolids by Manual Colorimetry.
Method 1687
This method is used to determine Total Kjeldahl Nitrogen in Water and Biosolids by Automated Colorimetry with Preliminary Distillation/Digestion.
Method 1688
This method is used to determine Total Kjeldahl Nitrogen in Water and Biosolids by Automated Colorimetry with Preliminary Semi-automatic Digestion.
Method 1689
This method is used to determine Ammonia-N in Water and Biosolids by Ion-Selective Electrode Potentiometry with Preliminary Distillation
Method 3050b
This method has been written to provide two separate digestion procedures, one for the preparation of sediments, sludges, and soil samples for analysis by flame atomic absorption spectrometry (FLAA) or inductively coupled plasma atomic emission spectrometry (ICP-AES) and one for the preparation of sediments, sludges, and soil samples for analysis of samples by Graphite Furnace AA (GFAA) or inductively coupled plasma mass spectrometry (ICP-MS).
Method 3051a
This microwave extraction method is designed to mimic extraction using conventional heating with nitric acid (HNO3), or alternatively, nitric acid and hydrochloric acid (HCl), according to EPA Methods 200.2 and 3050.
Method 6010b
INDUCTIVELY COUPLED PLASMA-ATOMIC EMISSION SPECTROMETRY. Inductively coupled plasma-atomic emission spectrometry (ICP-AES) determinestrace elements, including metals, in solution. The method is applicable to all of the elements listed and those required by 503.Revision 2December 1996
Method 6020
INDUCTIVELY COUPLED PLASMA - MASS SPECTROMETRY. Inductively coupled plasma-mass spectrometry (ICP-MS) is applicable to the determination of sub-µg/L concentrations of a large number of elements in water samples and in waste extracts or digests including those listed in 40 CFR 5034. Revision 0September 1994
Method 1668, Revision A
This method is for determination of chlorinated biphenyl congeners (CBs) in water, soil, sediment, biosolids, tissue, and other sample matrices by high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS).Method 1668 was developed by the U.S. Environmental Protection Agency's (EPA's) Office of Science and Technology for congener-specific determination of the polychlorinated biphenyl (PCB) congeners designated as toxic by the World Health Organization. Revision A of Method 1668 has been expanded to include congener-specific determination of more than 150 chlorinated biphenyl (CB) congeners.
Method 7000a
This method determine concentrations of inorganic constituents through the atomic absorption.
Method 7061a
