Preparation Note
The PT sample size provide is 25 g of soil. The soil has been preserved with 25 mL of methanol. The PT sample has been sized to 100 mesh. Required storage condition is 4º C. The sample has been intentionally prepared with an apparent headspace. The sample was fortified with a blended gasoline from three different refineries located the Rocky Mountains to be extracted and analyzed using method WI GRO. This sample can also be analyzed by other methods including but not limited to EPA 8015M, NWTPH Gx, and IOWA OA-1. The carbon chain of interest is C6 to C12. If you analyze for a different range as dictated by your analysis method you must indicate that range on the report form.
Sample Preparation
The 25 g soil PT sample is preserved in 25 mL methanol.
