The liquid-liquid microextraction and gas chromatography-mass spectrum(GC-MS)were applied to evaluate the contribution of the volatile organic acids to the aroma of Cabernet Gernischt wine.

A method for rapid determination of β-phenylethanol in fermentation broth was developed using combination detection of liquid-liquid microextraction(LLM)and gas chromatography, by which the effects of different yeast strains and different raw materials on β-phenylethanol production were studied.

Using methyl tert-butyl ether as extractant,the concentration of di-(2-ethylhexyl)-phthalate(DEHP) in water was rapidly determined by liquid-liquid micro-extraction and gas chromatography with hydrogen flame ionization detector(FID).

A rapid method for the determination of trace phenolic compounds including 2-methylphenol,2-nitrophenol and 2,4-dichlorophenol in water samples by liquid-liquid-liquid microextraction(LLLME) coupled with HPLC was developed.

High performance liquid chromatography coupled with liquid-liquid-liquid microextraction was developed for the simultaneous determination of sildenafil and vardenafil in human plasma.

The Technique and Application of Hollow Fiber Liquid Phase Microextraction;

Extraction of citric acid in multi-matrix by liquid phase microextraction;

Determination of dichloromethane and trichloromethane residues in ranitidine hydrochloride by headspace liquid phase microextraction coupled with gas chromatography

For each LPME operation mode,the recent developments of liquid phase micro-extraction were reviewed in terms of basic principle and mass transfer model.

A novel method for fast separate and enrichment imidacloprid in paddy,leaf,water and soil was established by using high performance liquid chromatography(HPLC) coupled with a three-phase hollow fiber based liquid phase micro-extraction(TP-HF-LPME) technique for sample preparation.
