PROBLEM TO BE SOLVED: To provide a column for collecting a carbonyl compound which can quickly, simply, inexpensively, excellently in reproducibility and efficiently collect the carbonyl compound, especially aldehydes to be provided to analysis while a recovering yield is highly maintained. SOLUTION: The column for collecting a carbonyl compound comprises a double-pore structure having through pores of range of numerical average diameter of 0.5μm to 25μm and mesopores of a range of a numerical average diameter of 2 nm to 50 nm, and filled with at least an inorganic filler of which the surface is coated with DNPH (2,4-dinitrophenylhydrazin).
