Abstract

A method for measuring formaldehyde emission from surfaces is described in which a test chamber in the form of an open reservoir of a gas-tight and waterproof material with a gel layer containing a reagent for formaldehyde applied on the inner bottom surface, is placed on the plain test surface with its opening facing the test surface, which reagent when reacting with formaldehyde emitted from the test surface generates a colour change of the gel substance, by means of which the amount of formaldehyde absorbed in the gel substance can be determined. A device for carrying out said method is also described, which comprises a test chamber, which consists of a reservoir, which can be a dish or similar container, the opening of the reservoir being considerably larger than the height of the reservoir, and wherein a gel layer containing a reagent for formaldehyde is applied over the whole inner bottom surface and wherein the opening of the reservoir is closable with a gas-tight and waterproof cap.
