“…Chen et al. [61] compared two extraction methods, followed by the analysis in a capillary LC with UV‐Vis detection. The separation was carried out in a C18 capillary column (500 μm id × 150 mm; 5 μm particle size), with a flow rate of 15 μL/min, and 254 nm detection wavelength.…”

Miniaturized liquid chromatography applied to the analysis of residues and contaminants in food: A review The humankind is pretty dependent on food to control several biological processes into the organism. As the world population increases, the demand for foodstuffs follows the same trend claiming for a high food production situation. For this reason, a substantial amount of chemicals is used in agriculture and livestock husbandries every year, enhancing the likelihood of contaminated foodstuffs being commercialized. This outlook becomes a public health concern; thus, the governmental regulatory agencies impose laws to control the residues and contaminants in food matrices. Currently, one of the most important analytical techniques to perform it is LC. Despite its already recognized effectiveness, it is often time consuming and requires significant volumes of reagents, which are transformed into toxic waste. In this context, miniaturized LC modes emerge as a greener and more effective analytical technique. They have remarkable advantages, including higher sensitivity, lower sample amount, solvent and stationary phase requirements, and more natural coupling to MS. In this review, most of the critical characteristics of them are discussed, focusing on the benchtop instruments and their related analytical columns. Additionally, a discussion regarding the last 10 years of publications reporting miniaturized LC application for the analysis of natural and industrial food samples is categorized. The main chemical classes as applied in the crops are highlighted, including pesticides, veterinary drugs, and mycotoxins.

“…Due to the complex nature of the sample in cosmetic products, pretreatment of samples is a very important step. For extraction of parabens are there many different methods, such as liquid phase microextraction, dispersive liquid-liquid microextraction (DLLME), solid phase micro-extraction (SPME), molecularly printed polymers extraction, stir bar absorbent extraction, solidified floating vesicular coacervative drop microextraction, and supercritical fluid extraction from different matrixes [8][9][10][11][12][13][14].…”

This study presents microextraction and determination of four parabens by vortex-assisted microextraction based on deep eutectic solvents (DESs) in cosmetic baby oils. The most suitable DES, ChCl-ethylene glycol mole ratios of DES were determined as 1:2 for use in this study. The effect of DES types has been explored at traditional one factor experiment at a time. The effect of DES volume, dilution solvent volume and vortex time on extraction recovery were examined and optimized by the Box-Behnken design. After optimum conditions were determined, vortex-assisted microextraction based on DES, 0.1-100 µg mL-1 concentration in the range of the calibration curve was plotted for all parabens. The recovery values of parabens in cosmetic baby oil samples were in the range of 82.02-101.95% and the RSDs were varied from 1.64% to 2.91%. This developed method is very suitable and effective method for the extraction of parabens from cosmetic products of similar structure.

“…Over the years various analytical techniques for the determination of parabens in different matrices have been developed, including gas-chromatography (GC) [ 9 , 15 , 16 ], high performance liquid chromatography (HPLC) [ 13 , 17 ], capillary zone electrophoresis (CZE) [ 4 ] and ultra performance liquid chromatography [ 18 , 19 ] amongst others. HPLC methods are the most widely used for the analysis and determination of parabens since techniques such as GC require prior derivatization of the compounds [ 20 ].…”

In this study, a simple, rapid and effective in-syringe micro-solid phase extraction (MSPE) method was developed for the separation and preconcetration of parabens (methyl, ethyl, propyl and butyl paraben) in environmental water samples. The parabens were determined and quantified using high performance liquid chromatography and a photo diode array detector (HPLC-PDA). Chitosan-coated activated carbon (CAC) was used as the sorbent in the in-syringe MSPE device. A response surface methodology based on central composite design was used for the optimization of factors (eluent solvent type, eluent volume, number of elution cycles, sample volume, sample pH) affecting the extraction efficiency of the preconcentration procedure. The adsorbent used displayed excellent absorption performance and the adsorption capacity ranged from 227–256 mg g−1. Under the optimal conditions the dynamic linear ranges for the parabens were between 0.04 and 380 µg L−1. The limits of detection and quantification ranged from 6–15 ng L−1 and 20–50 ng L−1, respectively. The intraday (repeatability) and interday (reproducibility) precisions expressed as relative standard deviations (%RSD) were below 5%. Furthermore, the in-syringe MSPE/HPLC procedure was validated using spiked wastewater and tap water samples and the recoveries ranged between from 96.7 to 107%. In conclusion, CAC based in-syringe MSPE method demonstrated great potential for preconcentration of parabens in complex environmental water.
