Application of the PTR-MS for the emission test of building products

During the emission testing of building products a large variety of organic compounds can be detected in air. THE PTR-MS principally allows monitoring the concentration development ("emission profile") of these compounds with a high time-resolution. In practice, the interaction of several compound spectra inhibits the reliable quantification of organic pollutants because the concentration of the measured ions results from a superposition of several compounds. If a compound with high fragmentation is present in the emission test chamber, that´s breakup cannot be prevented by changing the measuring conditions, the PTR-MS data is associated with a high error in qualification.
