Title:
HUMIDIFICATION-TYPE HIGH-SENSITIVITY/HIGH-SELECTIVITY AMMONIA DETECTION METHOD USING NANOMECHANICAL SENSOR, AND DETECTION DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/255580
Kind Code:
A1
Abstract:
The purpose of the present invention is to detect ammonia in a highly sensitive and highly selective manner by using a nanomechanical sensor and a structure that it as simple as possible. In the ammonia detection method according to one embodiment of the present invention, a sample gas possibly containing ammonia is supplied to a nanomechanical sensor that uses poly(methyl vinyl ether-alt-maleic anhydride) as a receptor layer material to detect stress or displacement, and the presence or absence of ammonia or the content amount of ammonia in the sample gas is detected on the basis of an output signal from the nanomechanical sensor. The ammonia detection method is characterized in that the sample gas is a humidified sample gas for which the relative humidity is controlled.
