Abstract

âº Nanostructured conducting polypyrrole (PPy) gas sensor was used as GC detector. âº The PPy gas sensor exhibited linear responses to pyridine derivatives. âº The GC/PPy gas sensor described facilitates fast, determination of pyridines. âº Dispersive liquid-liquid microextraction combined with gas GC/PPy gas sensor. âº The GC runs were completed in 4Â min for extracted analytes from cigarette smoke.
