Abstract

A self-contained, hand-held, optical waveguide, chemical detection system has been built to detect and quantify gases and vapors. The system uses a hybrid integrated circuit (IC) containing optical waveguides coated with sensing chemistry as the optical platform. The IC with sensing chemistry is available commercially under the name Sensor-on-a-Chip. This IC is mounted in a small, uniquely designed sample chamber where the measured analyte is identified by the sensing chemistry and biochemistry. Continuous or stop-flow sampling is possible. Sensitivities in the low parts-per-million have been attained for hydrocarbons and alcohol. Analyte coverage is only limited by the sensing chemistries and biochemistries that are available.
