Automated Sample Cleanup for Pesticide Multiresidue Analysis. Part II—Design and Evaluation of Column Chromatography Module
Keyword(s):
Abstract An automated, continuous flow system is described for Florisil column chromatography of pesticide residues from food extracts. Evaluation of the system using 5 common organochlorine and organophosphorus pesticides in 2 crop matrices demonstrates essentially no difference in recovery or precision between automated and currently used manual analyses. The automated procedure uses only 20% of the solvents and adsorbents used in the manual procedure and is 3 times faster.
