Combination of Thin Film Microextraction and Dispersive Liquid-Liquid MicroextractionMethod Followed by Ion Mobility Spectrometry for Analyzing of Chlorpyrifos Pesticidefrom Food and Water Samples

A novel configuration for the combination of the dispersive liquid-liquid microextraction method basedon the total vaporization procedure and thin film microextraction was used to extract of chlorpyrifos compound(as the model compound). Corona discharge ionization-ion mobility spectrometer (CD-IMS) was utilized as anidentification system. The limit of quantification and limit of detection were obtained at ۰.۱ and ۰.۰۳ μg L-۱,respectively.
