Abstract: The present invention provides a combinatorial approach for preparing arrays of chemically sensitive polymer-based sensors which are capable of detecting the presence of a chemical analyte in a fluid in contact therewith. The described methods and devices comprise combining varying ratios of at least first and second organic materials which, when combined, form a polymer or polymer blend that is capable of absorbing a chemical analyte, thereby providing a detectable response. The detectable response of the sensors prepared by this method is not linearly related to the mole fraction of at least one of the polymer-based components of the sensors, thereby making arrays of these sensors useful for a variety of sensing tasks.

Abstract: A package comprising an inner box and an outer box and provided with a hanger device for placing the package as an integral unit onto a horizontal support.The hanger device is formed by an extending end of a plate-shaped element arranged for insertion between the inner box and the outer box. The plate-shaped element is dimensioned for covering the major part of the broad side of the package.There are fixation means formed by said plate-shaped element for removably mounting said boxes to said plate-shaped element.
