“…Numerous analytical methods for determining penconazole, promecarb and phenothrin residues in various matrix have been published. Analyses of pesticides have been based on chromatographic and spectroscopic methods [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Before penconazole, promecarb and phenothrin residues were determined, samples required sample preaperation part (extraction and purification) [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

A sensitive method for the determination of phenothrin, promecarb and penconazole residues in tobacco has been developed. Several solvents such as, hexane, ethyl acetate and dichloromethane were tested in order to minimize agricultural products residue. In the study, the best recovery was achieved with dichloromethane. Pesticides residues are extracted from the samples with dichloromethane. Additional clean-up steps are not required for tobacco matrices. Determination and quantification of phenothrin, promecarb and penconazole are performed by gas chromatography-flame ionization detector (GC/FID) and gas chromatography-nitrogen/phosphorus (GC/NPD). The method has been validated for tobacco matrices. Under the optimum conditions, phenothrin R 2 value 0.999, promecarb R 2 value 0.999, and penconazole R 2 value 0.999. Limits of determination were 0.008 µg mL-1 for phenothrin, 0.011 µg mL-1 for penconazole and 0.007 µg mL-1 for promecarb. The standard deviations (SDs) levels were in the range 0.01-0.20. Recoveries of phenothrin, promecarb and penconazole from tobacco were found to be higher than 85%. Under this developed method, the concentrations of phenothrin, promecarb and penconazole in the 10 tobacco samples were below the LOD values.

“…In a recent study, we showed that this is due to the combination of two factors: the formation of reagent ions is energetically of low cost and the storage of reagent ions is more efficient than with other "classical" reagents. 11 Isobutane CI has been used in environmental analysis for the detection of insecticides 48,49 and pesticides. [50][51][52] It has also been widely used in medical and veterinary research as well as in analytical toxicology for the detection of propafenone (antiarrhythmic agent) 53 animal drug residues, 54 cocaine, 55 cannabidiol 56 and their metabolites.…”

This article presents the specificities of low pressure chemical ionization in ion trap mass spectrometry. One main feature is the ability to perform chemical ionization with liquid reagents as readily as with "conventional" gases (methane, isobutane and ammonia). The reactivities and analytical applications of gas and liquid reagents are summarized from literature data and are compared when possible.

The objective of this study was to elucidate the utility of ion-trap GC/MS/MS for the analysis of pesticides in extracted matrices from various agricultural products. Identification and quantitative analysis of pesticides in matrices were performed by quadrupole GC/MS and ion-trap GC/ MS/MS. Chlorpyrifos was added to the matrix of spinach, soybean in the pod or corn, and aldrin, dieldrin, endrin, a-BHC, b-BHC, g-BHC, d-BHC, p,p῎-DDDῌ p,p῎-DDE, o,p῎-DDT and p,p῎-DDT were added to each matrix of green tea, black tea or oolong tea. Although most of the pesticides in the matrix could not be determined by quadrupole GC/MS-Scan analysis at 0.1 mg/mL, every pesticide was identified from the mass spectrum using ion-trap GC/MS/MS at the same concentration. The quantitation limit of every pesticide in each matrix by ion-trap GC/MS/MS analysis was higher than that by GC/MS-SIM analysis. The calibration curves obtained by GC/MS/MS were linear in the range of 0.01ῌ0.25 mg/mL of each pesticide. The recoveries of each pesticide from four kinds of samples spiked at the levels of 0.01 ppm to 0.02 ppm in extracts were 61.2ῌ138.3 with SD values in the range from 1.2 to 15.4. This study revealed that ion-trap GC/MS/MS was useful for the identification and quantitative analysis of low-level pesticides residues in matrices of agricultural products.
