Continuous ultrasound-assisted extraction coupled to on line filtration–solid-phase extraction–column liquid chromatography–post column derivatisation–fluorescence detection for the determination of N-methylcarbamates in soil and food

Ionic liquid-dispersive liquid–liquid microextraction for the simultaneous determination of pesticides and metabolites in soils using high-performance liquid chromatography and fluorescence detection

“…In the work of Xiong and Hu [17], who analyzed six organosulfur pesticides by DLLME-GC-FPD, the LOD obtained for TZ (the only pesticide in common with this work) was approximately 23 ng/g (authors only provided LODs of the method for waters), which is also in accordance with the ones of our work. Results obtained in this work are also similar or even better to the ones obtained analyzing some of these compounds in soils using different techniques [7,[38][39][40][41][42][43][44]. Only in two of them [41,42], a lower LOD than in the present work was obtained for CB.…”

Simultaneous determination of carbamate insecticides and mycotoxins in cereals by reversed phase liquid chromatography tandem mass spectrometry using a quick, easy, cheap, effective, rugged and safe extraction procedure

“…It is well known that LC with fluorescence detection after derivatization was the most widely used quantitative method for carbamate insecticides and mycotoxins in the past due to their physical chemical properties, such as polarity [26,27]. Now, LC-MS/MS is an excellent alternative technique for the analysis of polar substances like carbamate insecticides and mycotoxins, because no derivatization step is required and higher selectivity and sensitivity can be acquired.…”

Analysis of Some Pesticide Residues in Cauliflower by High Performance Liquid Chromatography

“…Analytical techniques such as Gas Chromatography (GC) and High Performance Liquid Chromatography (HPLC) are widely used to monitor the presence of these compounds in water, soils, foods, fruits and vegetables. Several recent papers have reported advances in this field [2,[3][4][5][6][7][8] . In the present study, a method employing HPLC with UV detection for the separation, identification and quantification of four widely used pesticides on cauliflower was developed and validated.…”
