Please contact us 55.2 all available analytes which can be tested by EPA Method Organic compound analytes, internal standards, and surrogates are extracted from a 1L sample by passing it through a disk or cartridge containing a solid matrix with a chemically bonded C18 organic phase [liquid-solid methoe LSE ].

Additional QC procedures are recommended. The concentration of each identified component is measured by relating the MS response of the mdthod ion produced by that compound to the MS response of the quantitation ion produced by a compound that is used as an internal standard. B Contamination from sample carryover: Rinsing apparatus replacing syringes and injection port liners as needed can minimize contamination.

Analyte CAS Number 1,3-Dimethylnitrobenzene Acenaphthene-d10 Alachlor Atrazine Benzo a pyrene Bis 2-ethylhexyl Adipate Bis 2-ethylhexyl Phthalate Chrysene-d12 Hexachlorobenzene Hexachlorocyclopentadiene Perylene-d12 Phenanthrene-d10 Simazine Triphenyl Phosphate Examples: A method detection limit MDL must be determined for each analyte.

Organic compound analytes, internal standards, and surrogates are extracted from a water sample by passing 1 liter of 55.2 water through a cartridge containing about 1 gram of a solid inorganic matrix coated with a chemically bonded Cl8 organic phase liquid-solid extraction, LSE. Organic compounds – Instrument used for this test: Compounds eluting from the GC column are identified by comparing their measured mass spectra and retention times to reference spectra and retention times in a data base.

Precision and accuracy values were generated primarily from 8 replicate analyses of fortified reagent water using a liquid-solid C extraction cartridges and a quadrapole mass spectrometer see Table 3 of the Mthod. For these latter analytes 8 replicate reagent water samples were analyzed, except for PCB 6 replicates and toxaphene 7 replicatesand except for bis 2-ethylhexyl phthalate and di-n-butyl phthalate for which 7 replicates of fortified tap water were analyzed.

This method provides procedures for the determination of a wide range of organic compounds found in finished drinking water, source water, or drinking water in any treatment stage. Extracts can be held up to 30 days.

Initial demonstration of laboratory capability followed by regular analyses of laboratory reagent blanks LRBslaboratory fortified blanks LFBsand laboratory fortified matrix samples.

Surrogate analytes, whose concentrations are known in every sample, are measured with the same methor standard calibration procedure. Please contact us for assistance.

Kelso, Washington Laboratory Method information displayed is provided for informational purposes only. The method contains a large amount of additional information.

No methox express or implied is made as to the website accuracy, completeness, or applicability such as the age of a method and whether or not it applies to your project. Reference spectra and retention times for analytes are obtained by the measurement of calibration standards under the methos conditions used for samples.

Please contact the webmaster here. Samples can be held for 14 days generally see Sample Handling section of the method for exceptions.

The organic compounds are eluted from the LSE cartridge with a small quantity of methylene chloride, and concentrated further by evaporation of some of the solvent. Organic compounds are extracted from the LSE with small quantities of ep acetate followed by methylene chloride with further evaporation of the solvent.

If you have suggestions for improvement, we would enjoy hearing from you. The test methods page continues to expand and improve. For chlordane data, see meethod and gamma-chlordane, and for PCBs see specific Aroclors.
