Title:
METHOD FOR SENSING AND DEVICE FOR MEASURING VOLATILE FATTY ACID
Document Type and Number:
WIPO Patent Application WO/2023/048076
Kind Code:
A1
Abstract:
The present invention provides a method and device for sensing a volatile fatty acid with high sensitivity and measuring a volatile fatty acid with high precision. This method for sensing a volatile fatty acid comprises mounting a sample that potentially includes a volatile fatty acid in a closed space in which water vapor coexists with a resistance measurement device for measuring an electrical characteristic arising from electrical resistance between at least two electrodes disposed adjacent to each other across a minute interval on an insulating substrate, measuring the electrical characteristic when the relative humidity of the space in the vicinity between the electrodes satisfies a humidity condition immediately before condensation forms between the electrodes, and comparing the obtained measurement result and reference data obtained under a prescribed condition.
