Current trends in sample preparation by solid-phase extraction techniques for the determination of antibiotic residues in foodstuffs: a review

Critical Reviews in Food Science and Nutrition, Journal Year: 2020, Volume and Issue: 61(20), P. 3361 - 3382

The presence of antibiotic residues in foodstuff has been growing concern recent years. They are associated with several adverse effects on human health such as the transmission antibiotic-resistant pathogenic bacteria through contaminated food, weakness immune system, allergic or toxic reactions and imbalance gut microbiota. Therefore, monitoring levels animal-derived food is necessary to guarantee safety products well public health. Since residual antibiotics trace which often lower than limits detection analytical instruments, sample preparation before analysis very important. This step an essential part process, especially for extraction chemical from a sample, preconcentration extract elimination any matrix interferences that may affect selectivity, sensitivity overall performance methods. Solid-phase (SPE) one most widely used techniques provides efficient reproducible method selective concentration target analytes complex matrices. objective this research was provide updated overview trends SPE over past five Different variations method, including solid-phase microextraction, stir bar sorptive extraction, dispersion, micro-solid-phase dispersive micro magnetic molecularly imprinted also given present study. review focused developments innovations tries improve efficiency, preparation.

Screening of Pesticides and Polycyclic Aromatic Hydrocarbons in Feeds and Fish Tissues by Gas Chromatography Coupled to High-Resolution Mass Spectrometry Using Atmospheric Pressure Chemical Ionization

Journal of Agricultural and Food Chemistry, Journal Year: 2014, Volume and Issue: 62(10), P. 2165 - 2174

Published: Feb. 21, 2014

This paper reports a wide-scope screening for detection and identification of pesticides polycyclic aromatic hydrocarbons (PAHs) in feeds fish tissues. QuEChERS sample treatment was applied, using freezing as an additional cleanup. Analysis carried out by gas chromatography coupled to hybrid quadrupole time-of-flight mass spectrometry with atmospheric pressure chemical ionization (GC-(APCI) QTOF MS). The qualitative validation performed over 133 representative 24 PAHs at 0.01 0.05 mg/kg. Subsequent application the method aquaculture samples made it possible detect several compounds from target list, such chlorpyrifos-methyl, pirimiphos-methyl, ethoxyquin, among others. Light (≤4 rings) were found both animal vegetable samples. reliable supported accurate measurements presence least two m/z ions spectrum together retention time peak, agreement reference standard. Additionally, search widened include other which standards not available, thanks expected protonated molecule and/or molecular ion APCI spectra. could allow tentative different those included validated list.

A review of micro-solid-phase extraction techniques and devices applied in sample pretreatment coupled with chromatographic analysis

Acta Chromatographica, Journal Year: 2020, Volume and Issue: 33(2), P. 99 - 111

Published: Aug. 8, 2020

Abstract Sample pretreatment is one of the most crucial and error-prone steps an analytical procedure; it consents to improve selectivity sensitivity by sample clean-up pre-concentration. Nowadays, arousing interest in greener sustainable chemistry has increased development microextraction techniques as alternative preparation procedures. In this review, we aimed show two different categorizations used micro-solid-phase extraction (μSPE) techniques. essence, first concerns solid-phase (SPE) sorbent selection structure: normal-phase, reversed-phase, ion-exchange, mixed-mode, molecular imprinted polymer, special (e.g., doped cartridges for specific analytes). The second a grouping commercially available μSPE products categories sub-categories. We present every device technology into classifications paying attention their historical actual state art. So, study aims provide state-of-the-art techniques, highlighting advantages, disadvantages, possible future developments pretreatment.
