Abstract

The invention provides a visual array chip for gas analysis and application thereof. According to the visual array chip, functional modules from No.1 to No.36 are arranged on a substrate according to an array distribution mode, and the functional modules are prepared by coating the substrate with porphyrin and dye modified by gold nano-particles, porous organic silicate, plasticizer and materials having specific response to aldehyde volatile organic compounds. The visual array chip can be used for detecting and analyzing at least one volatile gas in benzene, methylbenzene, p-xylene, trimethylbenzene, trichlorofluoromethane, propyl aldehyde, hexanal, acetaldehyde, heptanal, acetone, 2-pentanone, tetrahydrofuran, heptane, decane, undecane, 1-hexene, isoprene, styrene, acetic acid, propionic acid, ethylenediamine, tetramethylethylenediamine, acetonitrile, propyl alcohol, thiol and butyl acetate compounds. The chip can be used for detecting multiple gas ingredients, has high sensitivity for detected objects with low detection limit, and can reach the ppbv detection level.

Description

technical field [0001] The invention belongs to the technical field of gas-sensitive visualized array chips, and in particular relates to a visualized array chip for gas analysis and its application. Background technique [0002] As a technology that is obviously different from traditional gas detection methods, array-based gas detection technology has attracted extensive attention from scholars. Among them, the array chip as the core component is particularly important in its composition and function. Previous sensing arrays mostly rely on weak intermolecular interactions between sensors and analytes, such as van der Waals forces and physical adsorption, which can be regarded as relative hydrophobicity between molecules in nature. Therefore, the intermolecular interactions of such array chips are relatively simple, and the detectable chemical properties are very limited, which not only limits the sensitivity of detecting low-concentration compounds, but also limits their s...
