Multisensor array for detection of analytes or mixtures thereof in gas or liquid phase

Abstract

The present invention relates to a multisensor array for detection of analytes in the gas phase or in the liquid phase, comprising at least two different chemo-selective compounds represented by the general formula (I) wherein the hetero atoms X-Xand the substituents R-Rare defined in the specification and the dashed bonds represent independently of each other either a single bond or a double bond. Said chemo-selective compounds are capable of individually changing physicochemical properties when exposed to analytes or analyte mixtures and these changes can be detected by a transducer or an array of transducers. The present invention does also relate to the use of at least two different chemo-selective compounds in a sensor array, a method for preparation of such sensor arrays and the use of said sensor arrays. Furthermore the present invention relates to methods for detecting and identifying analytes or mixtures thereof in the gas phase or in the liquid phase.
