7.0 PROCEDURE 7.1 Water, soil/sediment, sludge, and waste samples requiring analysis for semivolatile and nonvolatile organic compounds (within this broad category are special subsets of analytes, i.e., the different groups of pesticides, explosives, PCBs etc.), must undergo solvent extraction ...
6.5 Fill a 40- or 60-mL VOA vial with soil from each sampling point to use for dry weight determination, sample screening, and for high concentration analysis (if necessary). Sample screening is optional since there is no danger of contaminating the headspace device because of carryover from...
METHOD 3050B ACID DIGESTION OF SEDIMENTS, SLUDGES, AND SOILS 1.0 SCOPE AND APPLICATION 1.1 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 ...
6.3 Samples should be stored field-moist at 4 ± 2EC until analysis. 6.4 Hexavalent chromium has been shown to be quantitatively stable in field-moist soil samples for 30 days from sample collection. In addition, Cr(VI) has also been shown to be stable in the alkaline digestate for up ...
All these materials must be demonstrated to be free from interferences under the conditions of the analysis by analyzing method blanks. Specific selection of reagents and purification of solvents by distillation in all-glass systems may be necessary. Refer to each method for specific guidance on ...
