    • MicroChemLab

      The MicroChemLab is a handheld chemical analysis system that combines sample handling, separation, and detection. MicroChemLab combines three cascaded stages; each realized using microfabricated components.

      Preconcentrator - Stage 1
      Preconcentrator
      Stage 1
      Separation - Stage 2
      Separation
      Stage 2
      Detection - Stage 3
      Detection
       Stage 3

      The discrimination power of analytical chemistry techniques may one day be realized with micro-analytical systems that combine sensors with means for collecting samples, preconcentrating them, and separating constituent species for identification and quantification. Work is underway to construct on-chip building blocks for these systems, including pumps, valves, preconcentrators, gas-chromatograph columns, and sensors.

      Stage one collects and concentrates samples.
      Stage two is a gas chromatography (GC) column used to achieve sample separations.
      Stage three is an array of surface acoustic wave (SAW) sensors used to detect the sample.
