Project Overview
The Surface Acoustic Wave Array Detectors technology employs one or more acoustic wave sensors using sorbent coatings to measure chlorinated hydrocarbons and other volatile organic compounds (VOCs).

Technology Description
Development of advanced technologies with real-time, on-site capabilities has been focused on detecting VOCs; this focus was caused by the potentially significant impact of use of such technologies because of the prevalent nature of VOC contamination in groundwater and soil at DOE sites as well as the many Records of Decision requiring their timely removal. The theme of bringing laboratory analysis capabilities to the field is central to the practice of ESC. Field analysis technologies used during ESC incorporate detection principles based on mass spectrometry, infrared absorption, and acoustic wave methods.
