• Description:
  Microfabricated gas chromatography (µGC) offers a powerful portable vapor analysis solution for various field applications. Here, we developed a microfluidically integrated architecture of a microfluidic photoionization detector (µPID) on a microfabricated column (µcolumn) via a silicon-on-insulator platform. By eliminating the off-chip interconnects, the microfluidically integrated column PID (iCPID) demonstrated a narrow peak width compared to the off-chip benchmark µPID. Furthermore, the iCPID sensitivity as a function of the bias voltage and temperature were characterized. Finally, an ultracompact (0.9 L, 0.9 kg), automated, and battery-operated µGC system without any benchtop components was constructed based on the iCPID. Rapid (2 min) isothermal separation of eight volatile compounds at room temperature was demonstrated. Description provided by NIOSH
