Abstract
Second, we have developed a muGPC that helps gas detectors sniff a trace amount of toxic vapors by increasing their concentration via adsorption and thermal desorption. Integration with electrostatic microvalves enabled the muGPC to achieve extremely small dead volumes and fast injection times while the power and energy required to run a microheater, a key component of the muGPC, were kept small. Another unique feature of the muGPC is the use of an array of microposts coated with thin metal-organic framework adsorbents permitting a small pressure drop across the chamber while maintaining a large surface-area-to-volume ratio. The optimization of designing the muGPC is discussed in the context of maximizing the preconcentration factor while minimizing the energy required for operation.
