Ferrofluid-based liquid-phase microextraction
Journal of Chromatography A, 2010A new mode of liquid-phase microextraction based on a ferrofluid has been developed. The ferrofluid was composed of silica-coated magnetic particles and 1-octanol as the extractant solvent. The 1-octanol was firmly confined within the silica-coated particles, preventing it from being lost during extraction.

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.

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 ...

The Role of Liquid-Phase Microextraction Techniques in Bioanalysis
Bioanalysis, 2015Sample preparation is one of the most challenging tasks in laboratories, particularly in what concerns biological specimens, since they cannot be directly analyzed. A considerable amount of time and effort is spent in the extraction of the analytes and their concentration in a solvent that is compatible with analytical instrumentation.

Reduction of extraction times in liquid-phase microextraction
Journal of Chromatography B: Biomedical Sciences and Applications, 2001Recently, we introduced a simple and inexpensive disposable device for liquid-phase microextraction (LPME) based on porous polypropylene hollow fibres. In the present paper, extraction times were significantly reduced by an increase in the surface of the hollow fibres.

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 ...

Liquid phase microextraction applications in food analysis
Journal of Chromatography A, 2011Over the last years, liquid-phase microextraction (LPME) in its different application modes (single drop microextraction, dispersive liquid-liquid microextraction and hollow fiber-LPME) has been increasingly applied for the extraction of both inorganic and organic analytes from different matrices. Its advantages over conventional extraction procedures (

Liquid-Phase Microextraction in Bioanalytical Sample Preparation
Bioanalysis, 2009Liquid-phase microextraction (LPME) emerged in the mid-to-late 1990s, facing up to the main shortcomings of the classical liquid-liquid extraction. Since its origin, this new technique has been in continuous development driven by its successful and widespread use in the analytical sciences. Its inherent properties, such as low sample volume requirement,

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.

Successive liquid-phase microextraction of acidic and basic analytes
Analytica Chimica Acta, 2022Practical biological and environmental samples always contain both acidic and basic substances, and the samples are always precious. Thus, separation of analytes with different nature from the same sample was of great significance. Successive liquid phase microextraction (sLPME) of acidic and basic analytes under optimal extraction conditions was ...
