制备说明
Description
- 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 the 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 TNI.
- 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.
储存及稳定性
