Quick-Turn Study - (non-scheduled proficiency test that is available at any time)

Preparation Note

The PT sample is a soil containing total petroleum hydrocarbons (TPH). The sample size provided is 100 g of soil. The soil has been sterilized to minimize degradation of the sample. The PT sample has been sized to 100 mesh. The evaluation of results will be based on study statistics as required by NELAC. The sample has been intentionally prepared with an apparent headspace.

Sample Preparation
The soil is to be extracted and analyzed using an appropriate extraction and analytical method for TPH, assuming a high concentration sample.
Mix well. No particle size reduction is necessary.
List the extraction technique and analytical method used for analysis of this sample.
Using the selected extraction technique and determinative methods, determine the concentration of TPH in the sample and report your results as mg/Kg on a dry weight basis on the analysis data sheet provided.
Do not correct the analytical results for matrix spike recovery bias. Determine moisture content and report on a dry weight basis.
