Abstract
The invention relates to a measuring instrument and method for detecting the content of oil, hydrocarbons and oxidizable gases in air or compressed air. In order to develop a measuring instrument for detecting the content of oil, hydrocarbons and oxidizable gases in air or compressed air, said instrument being suitable for detecting concentrations in the lower μg/mrange or in the ppb range and allowing measuring accuracy of 10 micrograms oil/mair at a measurement error in the single-digit percentage range, it is proposed according to the invention that the measuring instrument comprises an air or compressed-air connection and, connected thereto, a flow limiter to which a catalyst is connected that is connected in turn with a photoionization detector, switchable means being provided for routing the air or compressed air over the oxidation catalyst or past it directly to the photoionization detector.
