Abstract

The present invention provides a chemical sensor comprising a substrate, a first colorimetric sensor array exposed and arranged in a first accommodating space of the substrate and a second colorimetric sensor array arranged in a second accommodating space of the substrate. The second accommodating space is covered with an isolating layer to isolates liquid molecules but allows gas molecules to pass through. The first colorimetric sensor array changes from a first initial color to a first indicating color according to a volatile part and a non-volatile part of an analyte, and the second colorimetric sensor array changes from a second initial color to a second indicating color according to the volatile part of the analyte, so that information of the volatile part and the non-volatile part of the analyte can be obtained simultaneously.

Description

technical field [0001] The present invention relates to chemical sensors, in particular to a chemical sensor with a colorimetric sensor array. Background technique [0002] Colorimetric sensor is a kind of chemical sensor, which uses the color conversion induced by chemical reaction to obtain the chemical information of the object to be detected. It has been widely used in environmental monitoring, food monitoring and other chemical monitoring fields. [0003] Conventional colorimetric sensors can be found in U.S. Patent Publication No. US20040184948A1, which discloses a colorimetric sensor for measuring one or both of the presence and concentration of an analyte, comprising: a substantially continuous reflective layer; covering a detection layer on said reflective layer, said detection layer comprising at least one polymeric component, said detection layer being capable of changing the optical thickness upon exposure to said analyte; and, overlying said The substantially c...
