Short summary
Benzene is a well-known carcinogen which is present in ambient air. Its concentrations have to be continuosly monitored by law. To obtain reliable and comparable measurements, benzene analysers have to be calibrated with standards. These standards are usually prepared without humidity. However, real measurements can be influenced by it. In this work we have found that ambient humidity has an effect on measurements, which depends on both the absolute humidity and the benzene concentration.
