An impinger collection/ion chromatographic source test method for formaldehyde was developed and evaluated. Unlike colorimetric methods for formaldehyde, ion chromatography is not subject to interference from phenol, which is present with formaldehyde in many source emissions. In addition, interferent tests showed that the ion chromatographic method is not subject to interference from trioxane, a stable formaldehyde polymer, or from hexamethylene tetramine, a frequently used source of formaldehyde in industrial processes.
