Popping candy-assisted dispersive liquid–liquid microextraction for enantioselective determination of prothioconazole and its chiral metabolite in water, beer, Baijiu, and vinegar samples by HPLC

Efficient analyses of triazole fungicides in water, honey and soy milk samples by popping candy-generated CO2 and sugaring-out-assisted supramolecular solvent-based microextraction prior to HPLC determinations

“…13 Very recently, popping candy-assisted dispersive liquid–liquid microextraction has been investigated. 14 In this method, the popping candy, which is produced from a mixture of sugar and high-pressure-compressed carbon dioxide, was investigated as a solid dispersant in the extraction process. No dispersant, which usually uses acetonitrile, methanol, and acetone as liquid dispersants, is necessary.…”

“…15 Consequently, it would be interesting to couple such approach to the chromatographic technique. The application for the popping candy in sample preparation was first reported by Jing et al 14 for the determination of prothioconazole and its chiral metabolite in water, beer, baijiu, and vinegar. In this work, a high temperature (90 °C) was applied.…”

Back‐extraction applied to green matrix solid‐phase dispersion for fungicides determination in tomatoes

“…Since foodstuffs are very complex matrices and pesticide residues are found in a very low concentration, before instrumental analysis sample pretreatments are necessary to isolate and enrich target analytes [13]. The most commonly used sample preparation techniques to extract triazole fungicides from tomatoes and other foodstuffs are QuEChERS and dispersive‐SPE [14, 15], however other techniques such as SPE [14], SPME [17], stir bar sorptive extraction [18] magnetic SPE [19], dispersive liquid‐liquid microextraction [10], single drop microextraction, air‐assisted liquid‐liquid microextraction [20] and matrix solid‐phase dispersion (MSPD) [21] have been employed. Among these, MSPD is a widely used technique to extract organic analytes from various matrices.…”

Hydrophobic microporous extraction on polyurethane sponges for convenient and sensitive analysis of organic molecules in water

“…Among the numerous sample pretreatment techniques, liquid‐phase microextraction (LPME) has attracted the attention of many researchers in the environmental, food, agricultural, and biomedical fields. For instance, depending on the form of the acceptor phase, LPME can involve single‐drop liquid microextraction (SDME), 1 solvent‐bar microextraction (SBME), 2–5 and/or dispersive liquid–liquid microextraction (DLLME) 6–9 . As a solvent‐minimized technique, LPME utilizes several microliters of organic solvents, and efficient enrichment occurs at the interface of the donor and acceptor phases.…”
