Determination of quinolone antibiotics in environmental water using automatic solid-phase extraction and isotope dilution ultra-performance liquid chromatography tandem mass spectrometry

Simultaneous determination of 13 sulfonamides at trace levels in soil by modified QuEChERS with HPLC-MS/MS

“…The LOD and LOQ were based on a signal-to-noise ratio of three (S/N = 3) and ten (S/N = 10), respectively. 26 The spiked recovery and precision were evaluated by analyzing three replicates of real soil samples at three levels (at 10, 20, and 100 μg kg −1 , respectively).…”

Recent Trends in Biosensors for Quinolone Detection: A Comprehensive Review

“…To detect and quantify trace amounts of antibiotics, either high-performance liquid chromatography (HPLC) alone or coupled with an elaborate detection system (HPLC-MS) is considered the gold standard to detect and quantify antibiotics in a variety of samples [2,48]. Such systems come with high sensitivity and the capability to analyze complex multi-quinolone samples [49][50][51][52][53][54]. Cavazos-Rocha et al developed a method using HPLC for the simultaneous quantification of multiple fluoroquinolones and oxazolidinone antibiotics in a mixed sample [54].…”

Effective extraction and determination of 24 quinolones in water and egg samples using a novel magnetic covalent organic framework combined with UPLC-MS/MS

“…Nevertheless, the complicated matrix and extremely low concentration of QNs in food and water samples can influence detection results; therefore, an effective sample pretreatment is indispensable. Common sample pretreatment methods include liquid–liquid extraction(LLE), 13 dispersive liquid–liquid micro-extraction (DLLME), 14 solid phase extraction (SPE), 15–17 dispersive solid-phase extraction (DSPE) 18,19 and magnetic solid phase extraction (MSPE). 20–22 Different from conventional sample pretreatment methods, MSPE is a dispersed solid-phase extraction technique that uses magnetic materials as adsorbents to achieve the separation and enrichment of analytes by an external magnetic field.…”
