Development of a new microextraction method based on elevated temperature dispersive liquid–liquid microextraction for determination of triazole pesticides residues in honey by gas chromatography-nitrogen phosphorus detection

Development of a more specific and accurate multiple reaction monitoring method based on GC–EI/MS/MS for simultaneously monitoring and determining 34 kinds of pesticides in Qianjinzhidai pills

“…Generally, there were five kinds of detectors used to monitor and determine pesticide residues according to the existing literatures when GC was applied as separation technique. They were nitrogen phosphorus detector (NPD) [5,6], electron capture detector (ECD) [7,8], flame ionization detector (FID) [9], flame photometric detector (FPD) [10] and mass spectrometry detector (MSD) separately. MSD had its unique advantages, which had stronger anti-interference, higher sensitivity, higher accuracy, better reproducibility, etc.…”

A Mobile-Based High Sensitivity On-Field Organophosphorus Compounds Detecting System for IoT-Based Food Safety Tracking

“…Another noise source is the thermal and 1/ noise of the operation amplifier which could be expressed in (8).…”

“…They can be generally divided into two categories, nonenzymes and enzyme-based methods [1]. The former methods mainly rely on physical and chemical ways without biological components involved, such as gas chromatography [2][3][4][5][6], nitrogen-phosphorus detection [7,8], high-performance liquid chromatography [9][10][11], and capillary electrophoresis [12]. Normally, these methods heavily depend on fussy instruments and are more suitable for in-laboratory detection.…”

Review on Extraction Procedures and Chromatographic Techniques for Analysis of Multiple Pesticides Residues in Honey

“…LLE was modified by using acidic extraction solvent mixture to avoid the co extraction of antibacterial sulfonamides with pesticides from honey {Gómez-Pérez, 2012 #11}. Certain solvent miniaturized LLE techniques like single drop micro-extraction (SDME), dispersive liquid liquid microextraction (DLLME) (Jovanov, Guzsvány et al 2014), air-assisted liquid-liquid micro-extraction (AALLME) (Farajzadeh, Mogaddam et al 2014), hollow fiber protected liquid phase micro-extraction (HF-LPME) (Yamini, Faraji et al 2015) have been developed and are used frequently to enhance the efficiency and reduce the organic waste generation. Tette et al, 2016 reviewed these techniques in detail {Tette, 2016 #8}.…”
