Title:
ACETONE DETECTING ELEMENT
Document Type and Number:
Japanese Patent JP2019196908
Kind Code:
A
Abstract:
To provide an acetone detecting element that can measure acetone included in the air with high accuracy and simplicity.SOLUTION: A detection solution 101 is produced in a vessel 102 by dissolving a 4-nitrophenylhydrazine as one of 2- or 4-functional phenylhydrazine compounds and a hydrochloric acid into a methanol, and then a porous material 103 being a porous glass having an average hole diameter of 4 nm, is soaked in the solution for 24 hours. A detecting element (acetone detecting element) 103a is made in a manner that, after the detection agent solution is impregnated in the holes of the porous material 103 in this way, the porous material 103 impregnated with the detection agent is air-dried, and is left to dry in a nitrogen gas stream for 24 hours. The detecting element 103a has the detection agent introduced which comprises the phenylhydrazine compound and the hydrochloric acid, and is supported with the detection agent in the porous holes of the detecting element 103a.SELECTED DRAWING: Figure 1
