Miniaturized instrumentation for field applications: general considerations for environmental sensor networks
Authors:Vahid Majidi  Christian Hassell
Institution:1. majidi@lanl.gov
Abstract:Various aspects of chemical instrument miniaturizing are explored. The limitations imposed by scaling laws are discussed, and the influences of system dynamics on chemical and physical behaviour of molecules in microsystems are presented. The complexity of chemical systems, as defined by intra- and intermolecular forces, influencing minimum device dimensions is illustrated for solution and gas-phase species. The basic concepts for environmental sensor networks are presented for a hypothetical system.
Keywords:Environmental sensor networks  Miniaturization  Detection limits
