Validated multiclass targeted determination of antibiotics in fish with high performance liquid chromatography–benchtop quadrupole orbitrap hybrid mass spectrometry

Screening of multi-class antibiotics in pork meat by LC-Orbitrap-MS with modified QuEChERS extraction

“…Later, a high percentage of organic reagents (95-100%) at the end of the gradient and relatively long washing intervals avoided carry-over phenomena. 21 In addition, we investigated the performance of different columns (BEH C18 column 1.7 mm, 2.1 mm  100 mm; CSH C18 column 1.7 mm, 2.1 mm  100 mm; HSS T3 column 1.8 mm, 2.1 mm  100 mm) for the separation of selected antibiotics. HSS T3 column provided satisfactory separation and peak shapes for selected antibiotics.…”

Silver Nanocatalyst Based Clock Reaction for Multi‐mode Detection of Tetracycline Antibiotics

“…[1][2][3][4] However, the residual problem of TCs and their metabolites in foodstuffs resulting from the drug abuse will cause seriously bad effects such as hepatotoxicity, gastrointestinal disorders, allergic reactions and drug resistance. [5][6][7] A number of analytical methods such as fluorescence, [8][9][10] high performance liquid chromatography tandem-mass spectrometry (HPLC-MS), [11][12][13][14] electrophoresis, [15][16] immunochromatography, [17,18] and enzyme linked immunosorbent assay [19][20][21][22] have been well developed for monitoring the levels of TCs residues, however, these reported methods always require expensive instruments and sophisticated operating procedures. Hence, the development of convenient and cost-effective assay for TCs is highly desirable.…”

Facile Synthesis of Reduced Graphene Oxide‐octahedral Mn3O4 Nanocomposites as a Platform for the Electrochemical Determination of Metronidazole and Sulfamonomethoxine

“…Traditionally, a range of analytical techniques have been developed for the determination of antibiotics, such as high-performance liquid chromatography [4,5], electrochemical sensing [6], immune assay [7], supercritical fluid chromatography [8], spectrophotometry [9], capillary electrophoresis [10], and gas chromatography-mass spectrometry [11]. Out of these methods, electrochemical sensing can provide faster analysis, simpler operation, higher sensitivity and lower cost [12,13].…”
