A carbonyl compound scavenger comprising a mineral acid salt of a benzylhydroxyamine-based compound of the formula (1) and at least one adsorbent selected from the group consisting of silica gel, alumina, cellulose and activated carbon: [wherein, R represents an alkyl group having 1 to 8 carbon atoms, haloalkyl group having 1 to 4 carbon atoms, alkoxy group having 1 to 4 carbon atoms, haloalkoxy group having 1 to 4 carbon atoms, nitro group or cyano group, and Rand Rrepresent each independently a hydrogen atom or alkyl group having 1 to 8 carbon atoms, and a hydrogen atom on a benzene ring to which a cyano group and R are connected may be substituted with an alkyl group having 1 to 8 carbon atoms, haloalkyl group having 1 to 4 carbon atoms, alkoxy group having 1 to 4 carbon atoms, haloalkoxy group having 1 to 4 carbon atoms, aryl group having 6 to 10 carbon atoms, nitro group or cyano group.].

Carbonyl compound scavenger and method of quantifying carbonyl compound using the same

A sampling material for a carbonyl compound in a gas comprising a reagent capable of converting a carbonyl compound to a derivative thereof supported on a cation exchanger; and a sampling cartridge for a carbonyl compound in a gas wherein a sampling material for a carbonyl compound in a gas comprising a reagent capable of converting a carbonyl compound to a derivative thereof supported on a cation exchanger is packed in a column are provided. The sampling cartridge can be used for analyzing a carbonyl compound such as formaldehyde with ease and at a high sensitivity and high accuracy, and has excellent storage stability.
