Development of microchip for rapid pretreatment of trichloroethylene and tetrachloroethylene volatilized from polluted soil.

Abstract

In the field of environmental analysis, microchip technology has many attractive features and is expected to realize the miniaturization of analytical instruments allowing on-site and multipoint monitoring using this technology. We propose a new soil analytical system for detecting trichloroethylene (TCE) and tetrachloroethylene (PCE) using a microchip. The experimental conditions for the pretreatment microchip were optimized. Under the optimized conditions, the detection limits of TCE and PCE were 15 and 9 ppbv, and the determination limits of TCE and PCE were 62 and 72 ppbv, respectively.
