“…applied with success an approach based on the combination of dispersive solid phase extraction (DSPE) with butylamide silica and CZE for the clean‐up/extraction and analysis of sulfamethoxazole in milk. The clean‐up capacity of DSPE using butylamide silica was similar to other SPE methods based on anion exchange or polymeric membranes in combination with HPLC . The determination of sulfamethoxazole, along with sulfadoxine, sulfamerazine, sulfisoxazole in milk samples was also carried out by Wang et al.…”

“…Sulfonamides are also an important family of antibiotics used in human and veterinary medicine for the treatment of different types of diseases. As it can be observed in Table , this kind of antibiotics have been analyzed by CE in different matrices like environmental water, milk, egg, honey, and fish . Recently, Zhang et al.…”

“…For this reason, several CZE methodologies reported in the literature were focused on the analysis of sulfonamides in food samples. For instance, three different CZE methods were developed for the analysis of sulfonamides in milk samples . Taking into account the complexity of this matrix, the use of clean‐up and preconcentration treatments is particularly relevant.…”

Natural, synthetic or semisynthetic antibiotics are highly used to prevent or treat diseases in humans and animals, and to promote animal growth. This fact makes that antibiotics residues or their transformation products may be present in food or in the environment after human or animal excretion. For this reason, it is imperative to develop reliable and sensitive analytical methodologies for their analysis. The main aim of this work is to present and discuss the most recent applications of capillary electromigration methods for the analysis of antibiotics, including the developments and applications of their use as chiral selectors in CE. The literature published from June 2015 to June 2017 is included following the previous review by Domínguez‐Vega et al. (Electrophoresis, 2016, 37, 189–211). Information about the use of different detection systems, off‐line and on‐line strategies to improve sensitivity, and microchip devices for the analysis of antibiotics is provided and properly discussed.

“…This improves analytical sensitivity, with the additional advantage of removing interferences [ 1 ]. Commonly employed preconcentration techniques include liquid-liquid extraction (LLE) [ 2 ], solid-phase extraction (SPE) [ 3 ], dispersive solid-phase extraction (DSPE) [ 4 ], magnetic solid-phase extraction (MSPE) [ 5 ], and quick, easy, cheap, effective, rugged, and safe (QuEChERS) [ 6 , 7 ]. These techniques are termed off-line .…”

Solid-phase extraction in combination with large-volume sample stacking-capillary electrophoresis (SPE-LVSS-CE) was applied to measure chlortetracycline, doxycycline, oxytetracycline, and tetracycline in milk samples. Under optimal conditions, the proposed method had a linear range of 29 to 200 µg·L−1, with limits of detection ranging from 18.6 to 23.8 µg·L−1 with inter- and intraday repeatabilities < 10% (as a relative standard deviation) in all cases. The enrichment factors obtained were from 50.33 to 70.85 for all the TCs compared with a conventional capillary zone electrophoresis (CZE). This method is adequate to analyze tetracyclines below the most restrictive established maximum residue limits. The proposed method was employed in the analysis of 15 milk samples from different brands. Two of the tested samples were positive for the presence of oxytetracycline with concentrations of 95 and 126 µg·L−1. SPE-LVSS-CE is a robust, easy, and efficient strategy for online preconcentration of tetracycline residues in complex matrices.

“…The design of methodologies for antibiotic determination in feedstuffs is necessary; quinolones, sulfonamides, and tetracyclines have acid–basic properties and adequate solubility in aqueous media; thus they are suitable to be analyzed by CZE, MEKC, or MEEKC. These methodologies have been commonly applied to analyze individual families of antibiotics, such as aminoglycosides, β‐lactams, quinolones, tetracyclines, and sulfonamides …”

Determination of antibiotics in feedstuff samples by microemulsion electrokinetic chromatography using fullerene as additive

et al. 2018

View full text Add to dashboard Cite

A microemulsion electrokinetic chromatography method was developed for the simultaneous detection and quantification of ciprofloxacin, norfloxacin, sulfamethoxazole, tetracycline, and oxytetracycline in feedstuff samples. The BGE composition was optimized by applying a Taguchi parameter design and consisted of phosphate 30 mmol/L, Tween-80 0.01 mmol/L, and fullerene 3 μmol/L, and adjusted to pH 8.0; the addition of surfactant and fullerene modifies the mobility of the analytes improving their resolution. Theoretical studies showed π-π and van der Waals interactions between antibiotic molecules and fullerene used as a pseudostationary phase. Under optimal conditions, limits of detection ranged from 0.7 to 1.5 μg/g; the analytes were separated in less than 6 min. The methodology proposed is useful for controlling and monitoring antibiotic residues in feedstuff samples.
