Preparation Note
NOTE: The reporting units have changed to μg/Kg for all analytes to meet NELAC requirements. The concentrations have remained the same. This standard consists of a 25-grams of soil containing volatile organics.
Sample Preparation
The sample is provided pre-extracted with methanol as specified by USEPA Method 5030.
Sample should be maintained at 4 °C. Shake sample for two minutes prior to opening.
Using a gas tight syringe, aliquot 100μL of methanol extract and inject into your purge and trap vessel below the surface of 5 or 25 mL of organic free water. Using more than 100μL may exceed the trapping capacity and detector response the purge and trap system.
After sampling, tightly reseal the vial ensuring there is no sample remaining between the vial rim, threads and cap. Immediately complete other sample preparation according to your analytical procedures.
To calculate your results, use 25 grams as the sample weight and 25 mL as the extraction volume.
Report results as μg/Kg Report on a wet weight basis, do not correct results for moisture content. On the provided report form, provide all of the requested information; note that the results of the analysis are to be reported on a wet weight basis.
In addition to all requested information, describe any unusual problems encountered in the extraction or analysis of the sample on the report form.
The method used must be reported. If multiple methods are used for preparation and/or analysis, a separate report form must be used for each preparation and analysis method.
