MEMS-Based Selective Preconcentration of Trace Level Breath Analytes

This paper presents high-performance micropreconcentrators (muPCs) aimed at breath analysis and a method for eliminating unwanted species from breath samples by using a two-step preconcentration procedure. The muPC consists of embedded high aspect-ratio three-dimensional (3-D) micro pillars coated w...
