THE EASY WAY TO PREPARE SOIL SAMPLES FOR THE FROG PORTABLE GC
The methanol extraction tool kit can be used to perform soil extraction and dilute waste solvents.
The scoopula is used to transfer soil into a weigh boat on the portable balance. Then the soil may be placed in a 20 mL VOA vial with 10 mL of methanol in it. After allowing the phases time to separate, the 100 μL syringe is used to inject the methanol extract into 5mL of water for analysis on the FROG portable gas chromatograph. If further dilution is required, the 10 μL syringe is used to transfer 10 μL into the 1 mL vials that contain 1 mL of methanol. These vials can also be used to serial dilute solvent wastes.
