Automated on-line solid-phase extraction methods in interlaboratory studies of polar pesticides in water samples

摘要

The use of automated on-line solid-phase extraction followed by liquid chromatography diode array or mass spectrometric detection for the determination of polar pesticides in water matrices is discussed. Emphasis is given to the participation in interlaboratory exercises organized in Europe by the Aquachek and the Measuring and Testing program of the European Union. Criteria of the coefficient of variation in interlaboratory exercises for polar pesticides in water is given. © 1997 John Wiley & Sons, Inc. Lab Robotics and Automation 9: 165–174, 1997.
