Rapid chromatographic separation and nanomechanical detection of thirteen mixed chemical compounds. Chromatograms from a NEMS resonator (top, blue) and a downstream FID detector (bottom, magenta) acquired simultaneously for comparison. The DKAP polymer-coated NEMS resonator showed high selectivity to organophosphate compounds such as DMMP, DEMP, and DIMP, as shown by the correspondingly strong peaks. Inset: Expanded view of the solvent peak, showing a 90% sensor recovery time of 40 ms.
