Solid drop based liquid-phase microextraction
Journal of Chromatography A, 2010Solid drop based liquid-phase microextraction (SDLPME) is a novel sample preparation technique possessing obvious advantages of simple operation with a high pre-concentration factor, low cost and low consumption of organic solvent. SDLPME coupled with gas chromatography (GC), high-performance liquid chromatography (HPLC), and atomic absorption ...

Headspace Water-Based Liquid-Phase Microextraction
Analytical Chemistry, 2005A new organic-free mode of headspace liquid-phase microextraction termed headspace water-based liquid-phase microextraction has been developed. Five phenols were used as model compounds in the development and evaluation of the procedure. Parameters affecting the extraction efficiency were investigated.

Gas flow headspace liquid phase microextraction
Journal of Chromatography A, 2009There is a trend towards the use of enrichment techniques such as microextraction in the analysis of trace chemicals. Based on the theory of ideal gases, theory of gas chromatography and the original headspace liquid phase microextraction (HS-LPME) technique, a simple gas flow headspace liquid phase microextraction (GF-HS-LPME) technique has been ...

Chemical reactions in liquid-phase microextraction
Journal of Chromatography A, 2009In recent years, liquid-phase microextraction (LPME), a microscale implementation of liquid-liquid extraction, has become a very popular sample pretreatment technique because it combines extraction and enrichment, and is inexpensive, easy to operate and nearly solvent-free.

Liquid-phase microextraction: update May 2016 to December 2018
Applied spectroscopy reviews (Softcover ed.), 2020Miniaturized extraction techniques are well established in analytical protocols following the guidelines of green chemistry. In spite of this, analytical chemistry researchers continue to look for alternatives and modifications that minimize or solve ...

Nanoparticle-enhanced liquid-phase microextraction
TrAC Trends in Analytical Chemistry, 2015Abstract Nanostructured materials play roles in different areas of analytical chemistry. Implementation of nanomaterials in liquid-phase microextraction results in a synergic combination yielding enhanced performance. Some significant examples include: carbon nanotubes for improving extraction efficiency; magnetic nanoparticles for retrieving ionic ...
