Sensor Microsystems

Sandia has developed a hand-held chemical analysis system. The instrument uses three microfabricated analysis stages. Stage one collects and concentrates the samples known as analytes. Stage two is a gas chromatography (GC) column used to separate the analytes.

Stage three is an array of surface acoustic wave (SAW) sensors used to identify and quantify the separated analytes.


We have developed a “hybrid” system, known as MicroChemLab™, where chemical separation (using a short column for rapid analysis with less resolution) is performed with the addition of an array of chemical detectors. This combination approach provides rapid and discriminating analyses. The MicroChemLab™ combines three cascaded stages; each realized using microfabricated components, (along with a miniature pump) for the analytical system.
