“…The usual techniques for isolating pesticides from fruit and vegetable samples are: liquid-liquid extraction (LLE), pressurized liquid extraction (PLE), liquid-liquid microextraction (LLME), microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE). Extract clean-up techniques are the most commonly employed solid-phase extraction (SPE), solid-phase microextraction (SPME), stir bar solvent extraction (SBSE) and gel permeation chromatography (GPC) [4]- [10]. Solid phase extraction (SPE) is currently the most popular extract clean-up technique [11].…”

Abstract-Applied all over the world, pesticides are some of the most common pollutants of the environment because of their stability, mobility, their consequent long-term adverse effects on living organisms in general and human health in particular. For these reasons it is essential to monitor and analyse pesticide residues in the fruits and vegetables. The analysis of food samples for the presence of pesticides causes a lot of difficulties in consideration of specificity of sample preparation based on multistage operations of purification of sample containing vestigial amount of analyte with simultaneous large amount of interferents. The extraction and determination of pesticide residues in fruit and vegetable samples are discussed, as are the techniques most commonly used in these processes. The difficulties occurring at each stage in the analytical procedure are outlined.

“…Vreuls et al [15] also reported satisfactory GPC separations of the triglycerides and the OP-pesticides using an azeotropic mixture of methyl acetate/ cyclopentane. In the present study the advantage of its lower boiling point (44 8C) was used to create a larger application range.…”

“…In our situation, often shooting of the solvent into the retention gap resulted in insufficient focusing of the OP-pesticides. The choice of the successful GPC clean-up procedure was already described by Vreuls [15], especially for this group of OP-pesticides with a broad range of polarities.…”

“…The use of GPC greatly reduces the downtime of instrument, extends column life and increases the analytical precision and accuracy [4][5][6]. In addition, GPC has indicated the potential for automated analysis with LC or GC; several groups have successfully introduced an automated GPC clean-up technique for the determination of pesticides [7][8][9]. However, considering the entire analytical process, much effort is still required to reduce analysis time and cost, such as reducing the consumption of solvent.…”

An automated online gel permeation chromatography-gas chromatograph mass spectrometer (GPC-GC/MS) was developed for the rapid determination of residual pesticides in agricultural products. Pesticides were extracted from homogenized food samples with acetonitrile and decontaminated via the matrix solid-phase dispersion (MSPD) technique, using a primary secondary amine as sorbent prior to GPC-GC/MS analysis. A slightly modified preparation method and automated GPC step proved useful in minimizing matrix interference. To evaluate the performance of the system, 97 target pesticides were spiked at a concentration of 0.1 mg/kg into a range of food types, including potato, cabbage, carrot, apple, orange, cucumber, and rice. A low flow rate of 0.1 mL/min in GPC resulted in a 40-fold reduction in solvent consumption compared with conventional GPC column applications. The combination of MSPD technique and GPC-GC/MS for the analysis of the 97 pesticides can be accomplished within 90 min. Most pesticides were recovered in the range of 70-120%, with relative standard deviation generally less than 10%. The results demonstrate that the method can be successfully applied with acceptable recoveries to a broad range of target pesticides within a diverse range of food types.
