The transient responses of quartz crystal microbalance (QCM) odor sensors coated with tert-butyl-calix [6] arene (calixarene) were analyzed. Calixarene is known as a molecule with a particular pot-like shape and large size. The sensor sensitivity is high because of its sensing film porous structure due to the large molecular size. The transient response, as generated by the application of a step variation in the concentration of the odor vapor, possesses useful information about the structure of the sensing film. The transient response can be modeled supposing a sum of two exponential decays with different time constants. The objective of this work is to study the relationship between the transient responses to the vapors and the sensing film structure. Calixarene was deposited as sensing film on a QCM by the Langmuir-Blodgett (LB) method at various deposition surface pressures. The deposition surface pressure modified the film structure and the transient responses. The results showed that the transient sensor response of calixarene film offers useful information for the separation and classification of odor/ gas samples.
