Zusammenfassung:	PURPOSE: An automatic total petroleum hydrocarbon (TPH) extracting system is provided to automate the extraction of THP from a soil sample, thereby increasing task reproducibility and extraction efficiency. CONSTITUTION: An automatic TPH extracting system (100) comprises a sample transferring unit (110), an ultrasonic wave extraction unit (120), a control unit (130), a solvent injecting unit (140), and a level sensor unit (150). The sample transferring unit is installed to be rotatable. The ultrasonic wave extraction unit is installed in the upper part of the sample transferring unit to be vertically moved and includes an ultrasonic extractor extracting THP existed in a soil sample (S). The control unit controls the movement of the ultrasonic extractor and the sample transferring unit. The solvent injecting unit injects a solvent into the soil sample. The level sensor unit senses the height of the solvent inside the soil sample. The control unit controls the height of the ultrasonic extractor based on the height information sensed by the level sensor unit.
