Abstract: This invention relates to a method of analyzing an aldehyde compound in a metal plating solution, including adding a pH control solution to an aldehyde derivative, thus preparing an oversaturated aldehyde derivative solution in which the aldehyde derivative is dissolved to be oversaturated while the pH of the aldehyde derivative solution is adjusted to be the same as that of the metal plating solution; adding the oversaturated aldehyde derivative solution to the metal plating solution, so that the aldehyde compound which is present in the metal plating solution undergoes derivation, thus obtaining an aldehyde derivative compound; extracting the aldehyde derivative compound; and analyzing the aldehyde compound from the extracted aldehyde derivative compound.
