PROBLEM TO BE SOLVED: To provide a method for quantifying formaldehyde concentration which enables accurate quantification, and a device for the method.SOLUTION: As a method for quantifying formaldehyde in gas, a method for converting formaldehyde into carbon dioxide to quantify the carbon dioxide is used, and formaldehyde concentration is calculated from difference in measurement values obtained before and after using an absorption column by inputting the absorption column for selectively absorbing an aldehyde ketone compound in a path. |
