Sorption, size-selective &amp; catalytic film or particle-bed filters dramatically enhance gas sensor selectivity. We critically review 300+ articles and tutorially give guidelines for systematic filter design in air quality, health &amp; food applications.

Highly selective gas sensing enabled by filters
