A Method for the Determination of Organochlorine and Organophosphorus Pesticide Residues on Tobacco/Eine Methode zur Bestimmung der Rückstände von Organochlor- und Organophosphor-Pestiziden auf Tabak

The methods currently used for the determination of pesticide residues on tobacco are compared to one another, and a new method is described which results from a combination of extraction and clean-up of the extract. For that purpose, a modified Soxhlet extractor is used which serves at the same time as clean-up column. The comparison to other methods shows clear advantages as regards saving of analysis time and consumption of solvents.
