The Gulf of Mexico oil spill is the largest offshore oil spill in U.S. history and great disaster. In situ and real-time monitoring the crude oil concentration is a critical topic after the oil spill. A new generation instrument is reported in this paper which miniaturizes the physical sizes while still maintaining the sensitivity of sensors. The key point is to miniaturize the extraction processing and also to integrate the extraction and detection on the same chip substrate. The sample handling and sensing units will be integrated on the chip itself and can be used as an independent and replaceable detecting head. The fabrication process of the device is introduced. Surface modification need to be done to keep extraction two phases stable. Other parameters of the device are well set. The test experiment result shows that this device can magnitude as high as 7 times concentration after 15 mins extraction.
