“…3), these results cannot be considered optimal due to recovery overestimation caused by the presence of matrix interferences. Dissimilar finding was revealed in study performed by Dias et al (2016) and Parrilla Vázquez et al (2016), who found EMR-Lipid superior to Z-Sep sorbent. However, this difference can be explained by the fact that the authors conducted experiments for samples of other edible oils than rapeseed oil, for different analytes, and with application of other instrumentation.…”

“…Additionally, novel EMR-Lipid (enhanced matrix removal-lipid) was taken into evaluation. This clean-up material was so far assessed for analysis of pesticides in kale, pork, salmon and avocado (Han et al 2016), olive oil, olives and avocado (López-Blanco et al 2016), as well as edible oils (Dias et al 2016;Parrilla Vázquez et al 2016;He et al 2017). In our study, EMR-Lipid removed less interference than 75 mg of Z-Sep, which is shown in overlaid chromatograms of blank samples obtained after application of both clean-up solutions (Fig.…”

This study develops a simple, cost-effective and sensitive high-performance liquid chromatography with diode array detector (HPLC-DAD) method for the simultaneous determination of eight sulfonylurea herbicides (oxasulfuron, metsulfuron-methyl, triasulfuron, chlorsulfuron, amidosulfuron, mesosulfuron-methyl, bensulfuron-methyl and tritosulfuron) in rapeseed oil. Extraction of target analytes was performed using quick, easy, cheap, effective, rugged and safe-based procedure followed by solid-phase extraction (SPE) and dispersive solid-phase extraction (d-SPE) cleanup, and presents good performance for all of the analytes with recoveries in the range of 67-133% and relative standard deviations (RSD) less than 15%. No significant matrix interference was observed due to the application of effective zirconium dioxide-based sorbent (Z-Sep). Method LOQs for most of the investigated analytes were set at satisfactory low value of 20 ng g −1 in food product. The procedure was evaluated in analyses of actual samples. The most important steps of the method optimization are presented. Novel EMR-Lipid cleanup solution for samples with high fat content was evaluated and compared to Z-Sep sorbent.

“…In recent studies, the combination of PSA+ C18, Z-sep alone (in SPE or d-SPE) and EMR have been compared. During the comparison studies, EMR was found good in term of % Recovery, reduction of matrix effect, %RSD and repeatability [14,16]. Moreover, EMR used in d-SPE gives good recovery even for the azole pesticides [14].…”

Pesticide residue analysis enables researchers to detect the minute quantity of residual pesticides by applying sensitive analytical techniques which include gas chromatography with mass spectrometry and liquid chromatography with mass spectrometry. However, the sample preparation step prior to utilizing these sophisticated techniques is key to achieving the required sensitivity. The present article reviews the significant methods available for sample preparation for pesticide residue analysis in edible oil. Present sample extraction and cleanup section, most common extraction and cleanup techniques such as liquid‐liquid extraction, solid phase extraction/dispersive solid phase extraction and quick, easy, cheap, effective, rugged and safe method are discussed. Since selection of sorbent affects the recovery, matrix effect and rate of false positive and false negatives, hence, special attention has been paid to sorbents required for sample cleanup. Many sorbents are commercially available however their possible interactions with fatty acids and impurities have not been highlighted in literature. The present review not only highlights the role of commonly used sorbents such as florisil, graphitized carbon black, primary secondary amine and octadecyl bonded silicas but also discusses the pros and cons of newly developed sorbents.
