Beschreibung
Zusammenfassung:	The invention relates to an analysis method for pesticide residues in plants. The method uses the interface device for the direct coupling of liquid chromatography and gas chromatography, called the TOTAD (Through Oven Transfer Adsorption Desorption) interface in scientific literature. The method only requires an extraction step prior to the chromatographic analysis. The pesticides are extracted from the sample with an organic solvent. Extract volumes that are much larger than those usually used are directly injected into the gas chromatograph, without needing any prior extract cleaning or concentration step. The TOTAD interface allows injecting extract volumes that are much larger than those normally injected into the gas chromatograph.
