Micro-analyzer with optical detection and wireless communications

There is a need to monitor chemical variables online in the environment and in industry. Novel online strategies are needed to optimize the measurement and control of these variables. This calls for the development of instrumentation systems capable of in situ measurements. This paper describes the development of a chemical micro-analyzer with an optical detection. The structure was manufactured using low temperature co-fired ceramics (LTCC) technology. The optical detection and the flow systems were integrated modularly to micro-analyzer and controlled by wireless communications. The continuous flow system was implemented with miniaturized actuators to provide autonomy and portability. The response of the optical detection was evaluated using a dilutions system by multi-commutation. The result was validated with a commercial instrument. The development described and proved in this paper would open up opportunities to new applications with wireless chemical micro-systems networks, a field with great potential. (C) 2013 Elsevier B.V.
