Liquid-Phase Microextraction or Electromembrane Extraction?

Analytical Chemistry, 2019
Isolation of substances by liquid-phase microextraction (LPME) or electromembrane extraction (EME) is becoming more and more important in analytical chemistry. However, the understanding of the mass transfer in LPME and EME is limited, especially for highly concentrated samples.

Hollow Fiber Liquid-Phase Microextraction

2012
This chapter discusses hollow fiber liquid-phase microextraction (LPME). The chapter comprises a short discussion of the basic setup and principles for LPME, and the historical development. The theory of LPME is also discussed including equations for extraction recoveries and extraction kinetics.

Development and evaluation of plunger-in-needle liquid-phase microextraction

Journal of Chromatography A, 2014
In this work, a novel, simple and fast one-step liquid-phase microextraction (LPME) approach, termed plunger-in-needle LPME was developed. In this method, the stainless steel plunger wire of a commercially available plunger-in-needle microsyringe was simply etched by immersion in hydrofluoric acid to form a microporous structure, and was used as the ...

Coupling solid-phase microextraction to liquid chromatography. A review

Analytical and Bioanalytical Chemistry, 2003
Solid-phase microextraction (SPME) is a technique for extraction of organic compounds from gaseous, aqueous, and solid matrices. SPME is rapid and simple, ideal for automation and for in situ measurements, and no harmful solvents are needed. The principle of SPME involves equilibration of the analytes between the sample matrix and an organic polymeric ...

Strategies for interfacing solid-phase microextraction with liquid chromatography

Journal of Chromatography A, 2007
Solid-phase microextraction (SPME) techniques are equally applicable to both volatile and non-volatile analytes, but the progress in applications to gas-phase separations has outpaced that of liquid-phase separations. The interfacing of SPME to gas chromatographic equipment has been straight-forward, requiring little modification of existing equipment.
