Emulsion-based liquid-phase microextraction: a review

Journal of the Iranian Chemical Society, 2013
In the past decade, liquid-phase microextraction (LPME), which can also be called solvent microextraction, has emerged as a minimal organic solvent-based sample preparation approach. The main advantages of this method include versatility, simplicity and effectiveness of its extraction procedures at reducing sample complexity, as well as the convenience

Dynamic headspace liquid-phase microextraction of alcohols

Journal of Chromatography A, 2005
A method was developed using dynamic headspace liquid-phase microextraction and gas chromatography-mass spectrometry for extraction and determination of 9 alcohols from water samples. Four different solvents, hexyl acetate, n-octanol, o-xylene and n-decane were studied as extractants.

Natural product applications of liquid-phase microextraction

TrAC Trends in Analytical Chemistry, 2019
Abstract As a simple, rapid, green, and highly-efficient sample-preparation technique, liquid-phase microextraction has been successfully coupled with various instrumental analysis methods and widely applied to determine target analytes (especially trace or ultratrace) from different natural products.

Two-phase hollow fiber liquid-phase microextraction

TrAC Trends in Analytical Chemistry, 2018
Abstract Hollow fiber based liquid-phase microextraction technique (HF-LPME) was proposed in 1999 as an efficient alternative to the conventional sample preparation methods. Since its initiation, this technique have become increasingly popular due to their simplicity, low cost, possibility of for automation, and adaptability to a wide variety of ...
