Correlation of human sniff tests and of analytical data with results from a hybrid modular sensor system

摘要

Experimental results of qualitative and quantitative analysis of packaging materials, and pharmaceuical emulsions obtained with a hydrid modular sensor system are presented. Two modules of the hydrid modular sensor system MOSES con5taining different transduction principles have been applied. In the present study 8 metal oxide-based sem8iconductor gas sensors (MOX) and 8 polymer coated quartz microbalance sensors (QMB) have been chosen. Pattern recongnition was performed by principal component analysis (PCA) and multicomponent analysis by principal component regressioin (PCR). The obtained results indicat e sufficient performance and reproducibitility of hybrid modular sensor s ystems for investiatioons of a broad spectrum of applications.
