“…Table 1 lists the relevant data, with the recovery rates ranging from 88.6% to 98.4%. Table 2 compares the obtained limit of detection, the relative standard deviation, the linear range, the recovery, and the correlation coefficient with those from ion pairing and reversed phase liquid chromatography [1], solid-phase extraction-HPLC [15], adsorptive stripping voltammetry [16], and CE [7]. The proposed method provides the similar extraction efficiency, whereas the detection limit of ENRO is lower than those from other methods.…”

The study based on the chemiluminescence (CL) reaction of potassium ferricyanide and luminol in sodium hydroxide medium, enrofloxacin (ENRO) could dramatically enhance CL intensities and incorporated with matrix solid-phase dispersion (MSPD) technique (Florisil used as dispersant, dichloromethane eluted the target compounds). A simple flow injection chemiluminescence (FL-CL) method with MSPD technique for determination of ENRO in eggs was described. Under optimal conditions, the CL intensities were linearly related to ENRO concentration ranging from4.0×10-8 g.L−1to5.0×10-5 g.L−1, with a correlation coefficient of 0.9989 and detection limit of5.0×10-9 g.L−1. The relative standard deviation was 3.6% at an ENRO concentration of2.0×10-6 g.L−1. Our testing technique can help ensure food safety, and thus, protect public health.

“…Pinero et al. investigated different sample treatments for the determination of penicillins (propranolol, metoprolol, and carvedilol) in bovine milk samples by CE, including offline (as SPE) and online preconcentration strategies (as LVSS). Sample treatment included protein precipitation prior to SPE preconcentration.…”

This contribution is a methodological review of the publications about the topic from the last 2 years. Therefore, it is primarily organized according to the methods and procedures used in surveyed papers and the origin and type of sample and specification of analytes form the secondary structure. The introductory part about navigation in the architecture of stacking brings a brief characterization of the various stacking methods, with the description of mutual links to each other and important differences among them. The main body of the article brings a survey of publications organized according to main principles of stacking and then according to the origin and type of the sample. Provided that the paper cited gave explicitly the relevant data, information about the BGE(s) used, procedure, detector employed, and reached LOD and/or concentration effect is given. The papers where the procedure used is a combination of diverse fragments and parts of various stacking techniques are mentioned in a special section on combined techniques. The concluding remarks in the final part of the review evaluate present state of art and the trends of sample stacking in CE.

“…To analyze FQs residues in a different matrix, many methods including capillary electrophoresis (27), immunoassays (2), high-performance liquid chromatography (22), liquid chromatography-tandem mass spectrometry (LC-MS/MS) were reported. Nevertheless, LC-MS/MS is considered as the most potent confirmatory method due to its high accuracy and sensitivity (3).…”

Enrofloxacin (ENR) is a broad-spectrum fluoroquinolone antibiotic widely used in both human medicine and veterinary medicine. In this study, the milk-excretion patterns of ENR and its metabolite ciprofloxacin (CIP) were determined up to the 10th milking following the intramuscular administration of ENR (2.5mg/kg of body weight) to lactating dairy buffaloes. The milk of each animal was collected and the concentrations of ENR and CIP were detected in milk by LC-MS/MS. The detection limits of the method were determined for ENR and CIP as 0.35 μg/kg and 0.12 μg/kg, respectively. The highest total mean concentrations of ENR and its metabolite CIP was determined in the second milking after injection as 603 μg/kg. The residue level in all buffalo milk samples was found to be lower than the maximum residue limit (100 μg/kg) at the fifth milking. In addition, the employed method is successfully applied to evaluate the presence of ENR and CIP residue in 50 marketed buffalo milk samples and none of the samples contained these antibiotics. Consequently, the present study provided information on the milk excretion levels of ENR and CIP in Anatolian buffalo milks by an LC-MS/MS method.
