Identification of aromas from alcohols using a Japanese-lacquer-film-coated quartz resonator gas sensor in conjunction with pattern recognition analysis

Computational Methods for the Analysis of Chemical Sensor Array Data from Volatile Analytes

“…For example, headspace samples of drink mixes allowed differentiation of genuine and faulty batches . Nanto and co-workers were successful in separating beverages based on responses obtained with an array of four quartz resonators . Targeted problems included samples with varying amounts of ethanol and samples with different types of alcohols.…”

Sensing behaviors of polypyrrole sensor under humidity condition

“…Among many different types of gas sensors [1][2][3], metal oxide [4] and conducting polymer type sensors are most popular. The conducting polymer sensors have great advantages of high sensitivity toward volatile organic compounds (VOCs) gases, a lower detectable limit in the range of a few tens of parts per millions, and the potential to operate at near room temperature [5].…”

Application of Linear Classifiers for Analysis of the Sensor Arrays Descriptiveness for Detection of the Volatile Compounds Molecules

“…Various types of classifiers are mentioned in the literature as applied to the analysis of multielement chemical sensor arrays responses [16]. Most popular of them are Prin-cipal Component Analysis (PCA) [17,18] and multilayer Artificial Neural Networks (ANN) trained by back propagation of error [19]. However, despite their wide spread occurrence, these methods do not provide complete solution of the classification problem.…”
