“…As can be seen, the chromatograms are clear, which means that the extraction procedure is effective and that the peaks are sharp and well resolved. For a complete analytical characterization, a comparison was carried out between our main results and those reported in the literature; in particular, recoveries, LODs and LOQs were compared between different studies performed in the last decade for the simultaneous analysis of PAEs and BPA in food/beverage matrices [51][52][53][71][72][73][74][75][76][77][78] (Table 4). As can be seen, the main basic PAEs analyzed in most papers are DEP, DBP, and DEHP together with BPA, whereas only a few papers show a more complete PAE speciation.…”

Phthalates (or phthalate esters, PAEs) and bisphenol A (BPA) are widely used in various industries, particularly in the fields of cosmetics and packaging, and they increase the malleability and workability of materials. As a result of their use, some international health organizations have begun to study them. In this study, the authors developed a methodology for the simultaneous determination of dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate (DiBP); dibutyl phthalate (DBP), bis(2-ethylhexyl) phthalate (DEHP); di-n-octyl-phthalate (DnOP) and bisphenol A (BPA) from drinking and non-potable waters. The extraction of PAEs and BPA was performed using a solvent-based dispersive liquid–liquid microextraction (SB-DLLME) method. The analytical determination was performed using a gas chromatography–ion trap mass spectrometry (GC-IT/MS) analysis. The entire procedure was validated as recoveries were studied according to the volume and the extraction solvent used, pH, and ionic strength. Dynamic linearity ranges and linear equations of all the compounds were experimentally determined as well as the limit of detection (LOD) (1–8 ng mL−1) and the limit of quantification (LOQ) (5–14 ng mL−1), reproducibility, and sensitivity. The method was applied to 15 water samples (mineral water and tap water) for determining PAEs and BPA released from the plastic container. After the release simulation, four PAEs (i.e., DiBP, DBP, DHEP, and DnOP) were determined at very low concentrations (below 1.2 ng mL−1) in two water samples from (sport) bottles.

Coupling of multiway and multiset modeling methods with hyphenated chromatographic data for second-order calibration purposes allows the quantification of multiple target analytes in highly complex samples, which otherwise would be impossible or at least a very hard task using univariate calibration scenario. In this regard, there are some chromatographic challenges that complicate attaining the best quantification efficiency through the highlighted advantages such as increased sensitivity and selectivity and the well-known second-order advantage. The present paper tries to overview these issues and to address the most usable strategies for their handling with a special focus on the relevant recent studies in quantitation field. KEYWORDS challenges, complex samples, hyphenated chromatography, multiway and multiset methods, quantitation 1 | INTRODUCTION One of the most important factors that enhances the quality of our life is the depth of our information about the composition of natural or synthetic materials, such as the presence of toxic or potentially dangerous substances in food products, personal care products, environmental resources, and so on. In fact, numerous similar and highly concerned examples can be noted, in addition to the cases that are recently spotlighted, like identification and quantification of new banned drugs in slimming herbal products.Chromatographic analytical systems have been widely used for analysis of complex samples, such as bioanalytical field, food analysis, and metabolomics. Hyphenated chromatographic techniques, such as high-performance liquid chromatography coupled with diode array detection or fast-scanning fluorescence detection (HPLC-DAD/FSFD), liquid chromatography mass spectrometry (LC-MS), and gas chromatography mass spectrometry (GC-MS), have found their place in most of analytical laboratories and routinely provide valuable qualitative and quantitative information. As a result, such powerful techniques enable the analyst to efficiently analyze much more complex samples of various nature. This is especially true for chromatographic systems coupled with mass spectrometric detection, because of additional selectivity and sensitivity, which is the intrinsic and advantageous property of mass spectrometers. However, parameter optimizations in chromatographic systems (especially in LC systems) is a necessary and often laborious step in the path to obtain the best performance of the instrument. In fact, success of the chromatographic separation, robustness and stability of the outcome signal, strongly depends on chromatographic equipment, such as pumping and solvent delivery system, detector performance, column type and its steadiness, and temperature control. Although some chromatographic troubles such as problematic solvent peak, a nonstable or nonuniform background offset, peak tailing or fronting, coelution of analytes with each other or matrix constituents, retention time shifts in different runs, peak shape changes, and a narrow linear response range may usually exist.Fi...

“…Considering the effects of endocrine disruptors on the human body, even at low concentrations, it is of crucial importance that analytical methods are developed to detect and quantify these compounds in a wide range of samples. These chemicals have been studied in distinct samples including urban wastewater [1, 12,13], bottled mineral water [2], beverages [4], indoor dust [7], human serum [8], and environmental water samples [6,9,10,[14][15][16]. The determination of these chemical substances is commonly performed by LC [4,6,8,10,[12][13][14][15][16][17], GC [1, 5,7], and CE [18,19].…”

Evaluation of two membrane-based microextraction techniques for the determination of endocrine disruptors in aqueous samples by HPLC with diode array detection

et al. 2017

In this study, the viability of two membrane-based microextraction techniques for the determination of endocrine disruptors by high-performance liquid chromatography with diode array detection was evaluated: hollow fiber microporous membrane liquid-liquid extraction and hollow-fiber-supported dispersive liquid-liquid microextraction. The extraction efficiencies obtained for methylparaben, ethylparaben, bisphenol A, benzophenone, and 2-ethylhexyl-4-methoxycinnamate from aqueous matrices obtained using both approaches were compared and showed that hollow fiber microporous membrane liquid-liquid extraction exhibited higher extraction efficiency for most of the compounds studied. Therefore, a detailed optimization of the extraction procedure was carried out with this technique. The optimization of the extraction conditions and liquid desorption were performed by univariate analysis. The optimal conditions for the method were supported liquid membrane with 1-octanol for 10 s, sample pH 7, addition of 15% w/v of NaCl, extraction time of 30 min, and liquid desorption in 150 μL of acetonitrile/methanol (50:50 v/v) for 5 min. The linear correlation coefficients were higher than 0.9936. The limits of detection were 0.5-4.6 μg/L and the limits of quantification were 2-16 μg/L. The analyte relative recoveries were 67-116%, and the relative standard deviations were less than 15.5%.
