Simultaneous Determination of Aminoglycoside Residues in Food Animal Muscles by Mixed-Mode Liquid Chromatography-Tandem Mass Spectrometry

Profiling cocaine residues and pyrolytic products in wastewater by mixed‐mode liquid chromatography–tandem mass spectrometry

“…These columns contain long alkyl chain ligands with an ionizable terminus which, depending on the functional groups and the pH of the mobile phase, allow them to interact with the analytes by anion‐exchange, cation‐exchange or both, in addition to RP interactions. Several applications of this technology can be found in the pharmaceutical field and, to a minor extent, in the food and environmental field …”

“…Several applications of this technology can be found in the pharmaceutical field [28][29][30] and, to a minor extent, in the food 31,32 and environmental field. 33,34 The aim of this study was to develop a new analytical method combining SPE and mixed-mode LC coupled to MS/MS for the determination of COC and its related compounds in wastewater.…”

Determination of antibiotics in meat samples using analytical methodologies: A review

“…AGs extraction from meat tissues usually involves the use of aqueous solutions containing ethylenediaminetetraacetic acid (EDTA; Arsand et al., 2016; J. Li et al., 2018; Saluti et al., 2018; Savoy et al., 2018; B. Yang et al., 2017), phosphate‐buffered saline (PBS; J. Li et al., 2018; B. Yang et al., 2017; Congcong Zhang et al., 2018) or ACN (H. Liu et al., 2020; C. Zhang et al., 2018), and other salts such as ammonium acetate (Saluti et al., 2018) conjointly with trichloroacetic acid (TCA) to precipitate and consequently remove proteins. Once in solution, different sample preparation methods, such as SPE (Arsand et al., 2016; J. Li et al., 2018; Saluti et al., 2018; Zhu et al., 2016), molecularly imprinted solid phase extraction (MISPE; Savoy et al., 2018; B. Yang et al., 2017), MSPE (H. Liu et al., 2020), and DSPE (Arsand et al., 2016) have been employed as cleaning, purification and enrichment step for the analysis of AG in meat samples. Generally, C 18 (Arsand et al., 2016), hydrophobic–lipophilic balance (HLB; Zhu et al., 2016), cation exchange (J. Li et al., 2018; Saluti et al., 2018; C. Zhang et al., 2018), and MIPs (Savoy et al., 2018; B. Yang et al., 2017) commercial sorbents have been used to extract AG with recoveries between 37% and 106%…”

“…To put SAs into solution, the solvent most commonly used is ACN (X. L. Chen et al., 2019; Z. Chen et al., 2019; Y. Li et al., 2018; X. Liu et al., 2020; Moga et al., 2020; Y. Wang et al., 2017; Zhao et al., 2020) combined with water (Nasir et al., 2019) or aqueous solutions containing phosphoric (Deng et al., 2016) or formic acids (Xia et al., 2020). However, other organic solvent combinations such as acetone–dichloromethane and acetic acid–ethyl acetate (Varenina et al., 2016), ethyl acetate–water (Premarathne et al., 2017), or only ethyl acetate (Dai et al., 2017; Govind et al., 2018) have been also used.…”

Once in solution, SAs preconcentration and purification techniques include LLE (Govind, Babu, Rao, Sriram, & Senthil, 2018; Premarathne, Satharasinghe, Gunasena, Munasinghe, & Abeynayake, 2017), DLLME (Deng, Lan, Sun, Ji, & Zheng, 2016), SPE (X. L. Chen et al., 2019; Z. Chen et al., 2019; Dai et al., 2017; Y. Li et al., 2018; Moga et al., 2020; Varenina et al., 2016), DSPE (Deng et al., 2016; Xia et al., 2020), DSPME (Y. Wang et al., 2017), MSPE (Liu, Tong, & Zhang, 2020; Xia et al., 2017; Zhao et al., 2020), magnetic solid phase microextraction (MSPME, Nasir et al., 2019), or the use of QuEChERS (Huertas‐Pérez et al., 2016; C. H. Wen et al., 2017). For cleaning and preconcentration step, commercial sorbents such as C 18 , amino adsorbent and neutral alumina (Deng et al., 2016), aromatic sulfonic acid (Varenina et al., 2016), and a polymeric strong cation exchange (Dai et al., 2017) have been employed.…”
