Ionic liquid-based microwave-assisted dispersive liquid-liquid microextraction and derivatization of sulfonamides in river water, honey, milk, and animal plasma.
TL;DR: The ionic liquid-based microwave-assisted dispersive liquid-liquid microextraction (IL-based MADLLME) and derivatization was applied for the pretreatment of six sulfonamides (SAs) prior to the determination by high-performance liquid chromatography (HPLC).

Determination of organophosphorus pesticides in peanut oil by dispersive solid phase extraction gas chromatography-mass spectrometry.
TL;DR: The organophosphorus pesticides including phorate, diazinon, tolclofos-methyl, fenitrothin, malathion, fenthion, isocarbophos, quinalphos and phenamiphos, in peanut oils were determined by liquid-liquid extraction coupled with dispersive solid phase extraction and gas chromatography-mass spectrometry (GC-MS).

Application of multiwall carbon nanotubes-based matrix solid phase dispersion extraction for determination of hormones in butter by gas chromatography mass spectrometry
TL;DR: The multiwall carbon nanotubes-based matrix solid phase dispersion (MSPD) was applied for the extraction of hormones, including 17-β-estradiol, estrone, medroxyprogesterone, progesterone and norethisterone acetate in butter samples and is simpler in the operation and shorter in the sample pretreatment time.

TL;DR: Twenty-one kinds of fruits including strawberry, mulberry, lemon, banana, etc. were measured for antioxidant capacity based on their ability to scavenge 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical to quantify Vitamin C equivalent antioxidant capacity.

Ultrasonic nebulization extraction coupled with on-line gas chromatography for determination of trans-anethole in spices.
TL;DR: Compared with off-line systems, the proposed on-line system is more suitable to detect volatile compounds and easier to be introduced into GC system than those in the solid and liquid phase.
