Abstract

The present invention relates to a device for detection of a gaseous analyte. Specifically, the present invention relates to a device for detection of a gaseous analyte, wherein the device is comprised of a first layer, being a substrate layer, a second layer, being an electrical insulating layer interposed between the first layer and a third layer, being a graphene layer and a fourth layer that is comprised of transition metal complexes, wherein the fourth layer is provided on a top surface of the graphene layer, wherein said transition metal complexes are capable to form a stable complex with said gaseous analyte. Furthermore the device comprises at least two electrodes being in electrical communication with the graphene layer and are capable of measuring a change in conductance of the graphene layer by measuring a change in electric potential between electrodes. Furthermore the present invention relates to methods for the detection of gaseous analyte and the use of the device of present invention to measure the gaseous analyte concentrations.

Abstract

A method for controlling an atmosphere in a space which is at least partially filled with agricultural or horticultural products comprises the steps of (a) measuring an amount of at least one metabolite such as acetaldehyde, ethyl acetate and/or ethanol produced by the products, (b) measuring at least one of (i) an amount of oxygen absorbed by the products and (ii) an amount of carbon dioxide produced by the products, (c) determining a relationship between the measured amount of the metabolite and the measured amount of oxygen and/or carbon dioxide, (d) analyzing the determined relationship to detect a potential onset of fermentation in the products and (e) selectively adjusting a level of at least one component of the atmosphere in the space on the basis of the analysis. An installation for carrying out this method is also claimed.
