A rapid screening method of styrene and tetrachloroethylene in olive oil based on membrane inlet mass spectrometry has been developed. The presence of these contaminants was identified and monitored on the basis of the mass spectra measured. Detection limits of 100 and 5 ppb were measured for styrene and tetrachloroethylene, respectively. A linear dynamic range of at least 3 orders magnitude was achieved. Fast response times, in the order of 1 min, for the analytes were observed, allowing large sample throughput
