“…Methanol, acetone, acetonitrile, dichloromethane, and ethyl acetate are solvents commonly used for the extraction of various pesticide and veterinary drugs, of which methanol is the solvent most used to dissolve and extract polar and nonpolar chemicals. In many previous studies, methanol has been widely used in the extraction of veterinary drugs, such as tetracyclines, macrolides, and sulfonamide antibiotics [ 14 , 26 , 27 , 28 , 29 , 30 ]. Extraction conditions are mainly associated with the physical and chemical features of the target compounds as well as the features of the solvents.…”

A method was developed for the rapid and quantitative analysis of 30 veterinary drugs belonging to 17 classes (amphenicols (1), anthelmintics (1), cephalosporins (4), coccidiostats (1), lincosamides (1), macrolide (1), nitroimidazole (1), penicillins (3), phenylhydrazines (1), polypeptides (1), pyrethrins (1), quinolones (5), sulfonamides (3), tetracycline (3), neuroleptic agents (1), triazene trypanocidal agents (1), other. (1)) in feeds. The proposed method with a modified Quick Polar Pesticides (QuPPe) sample preparation was validated for the determination of 30 veterinary drugs in feed samples by liquid chromatography triple-quadrupole mass spectrometry (LC–MS/MS). The sample was extracted with methanol containing 1% acetic acid and purified by dispersive solid-phase extraction (d-SPE) with C18. Good linearity (r2 ≥ 0.98) was observed, and the LOQ values ranged from 10 to 200 µg/kg. Average recoveries ranged from 70.8 to 118.4%, and the relative standard deviation was ≤ 18.7%. This validated method was used in the determination of 30 veterinary drugs in 142 feed samples obtained from South Korea. The results show that lincomycin was present in only one of the tested feed samples, although it was detected at a value lower than the LOQ. In conclusion, this multi-residue method can be used for screening through the detection and quantitation of residual multiclass veterinary drugs in feed samples.

“…To mill cryogenically, as suggested by QuPPe, can prevent this from happening [ 3 ]. Oil and nuts are representative food samples in this category [ 11 ]. The high oil/lipid content QuPPe sample pretreatment process is the same as the procedure for low-water content commodities but additional clean-up steps are needed in which the sample is extracted with n-hexane and then cleaned up with a C18 sorbent [ 11 ].…”

“…The development of a method that permits different HPP compounds to be simultaneously analyzed since various pesticides are used in foods during their cultivation. Over the years, reversed-phase chromatography (RPC) [ 11 , 12 ], hydrophilic interaction liquid chromatography (HILIC) [ 13 , 14 ], ion chromatography (IC) [ 9 , 15 ] and mixed-mode chromatography (MMC) [ 16 ] have been studied for the separation of HPP compounds. In the case of reversed-phase chromatography, there are two approaches for the separation of HPP including HPP derivatization or stationary phase modification.…”

Highly polar pesticides (HPP) are a group of pesticides that are characterize as low Log Kow. Many high-throughput multi-residue analysis methods based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the simultaneous determination of such polar pesticides have been proposed. In this article, we summarize the various sample preparation methods including quick polar pesticides (QuPPe), dispersive solid phase extraction (dSPE), solid phase extraction (SPE) and QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe), especially for QuPPe, which are mainly used for the determination of HPP in foods. In addition, we summarize LC-based separation methodologies that are currently used for the analysis of HPP in foods, including reversed-phase chromatography (RPC), hydrophilic interaction liquid chromatography (HILIC), ion chromatography (IC) and mixed-mode chromatography (MMC). Finally, the current mass spectrometry-based methodologies for the analysis of HPP are summarized with a specific focus on MS configurations and acquisition modes.

“…There are various approaches for the analysis of anions in water, soil and air, including liquid chromatography, 14 mass spectrometry, 15 surface-enhanced Raman scattering, 16 and capillary electrophoresis. 17 Although these techniques provide good accuracy and sensitivity, they are severely limited for onsite analysis owing to the tedious sample preparations, bulky and expensive instrumentations, and susceptibility to the interference of coexisting anions.…”
