Development of a Methodology for the Determination of Pesticide Residues in Cajá-Manga Pulp (Spondias dulcis L.) Using Solid-Liquid Extraction with Low-Temperature Partitioning

Figure 6

Separation of pesticide residues extracted from the cajá-manga pulp by the SLE-LTP method, using gas chromatography with flame ionization detection. Conditions: capillary column 30 m × 0.32 mm i.d. × 0.25 µm film thickness, 5% phenylmethylsiloxane-95% dimethylsiloxane, split injection 1 : 5, injected volume 1 µL, injector temperature 280°C, FID temperature 300°C, N₂ flow rate 1.5 mL·min⁻¹, and oven temperature 100°C (1 min), 25°C min⁻¹, 200°C, 40°C min⁻¹, 300°C (4.5 min). (1) Chlorpyrifos; (2) thiabendazole; (3) carboxin; (4) difenoconazole.
