AB  - A quartz crystal microbalance sensor coated with a thin film of pollyaniline/carbon nanotubes was
used as a sensitive method for the determination of a number of following vapours: Ethyl acetate, chloroform,
ammonia. The detections were based on the absorptions of vapours of these organic compounds into the film
by using gas cell room. The detection of vapours were obtained in part per million ppm. The research includes
the use of polyaniline films with different thickness 64, 94, 124 and 186 nm where thickness of the
(Poly aniline/MWCNT) films was controlled by spin coater. Results show that increasing of sensitivity with
increase of the concentration of injected analyte when the (Poly aniline/MWCNT) nano-film-coated QCM was
exposed to the vapours of ethyl acetate, chloroform, ammonia. Best sensitivity to ammonia were obtained with
film thicknesses 94 nm while in the case of.
