Membrane-based microextraction techniques in analytical chemistry: A review

Analytica Chimica Acta, 2015
The use of membrane-based sample preparation techniques in analytical chemistry has gained growing attention from the scientific community since the development of miniaturized sample preparation procedures in the 1990s. The use of membranes makes the microextraction procedures more stable, allowing the determination of analytes in complex and "dirty ...

Solvent-free microextraction techniques in gas chromatography

Analytical and Bioanalytical Chemistry, 2011
Microextraction techniques represent a major part of modern sample preparation in the analysis of organic micropollutants. This article provides a short overview of recent developments in solvent-free microextraction techniques. From the first open-tubular trap techniques in the mid-1980s to recent packed-needle devices, different implementations of in-

Microextraction sample preparation techniques in biomedical analysis

Journal of Separation Science, 2014
Biologically active compounds are found in biological samples at relatively low concentration levels. The sample preparation of target compounds from biological, pharmaceutical, environmental, and food matrices is one of the most time‐consuming steps in the analytical procedure. The microextraction techniques are dominant.

Advances in Automated Piston Liquid-Liquid Microextraction Technique

Journal of Chromatography A, 2021
A new automated micro liquid-liquid extraction technique was successfully developed. This novel syringe-based technique capitalizes on the advantages of vigorous fluid agitation and the shearing effect of two fluids with different properties to achieve high extraction efficiency.

Microextraction techniques in the analysis of food flavor compounds: A review

Analytica Chimica Acta, 2012
Food flavor compounds due to the complexity of food as a matrix, and usually their very low concentrations in a product, as well as their low odor thresholds, create a challenge in their extraction, separation and quantitation. Food flavor volatiles represent compounds of different polarity, volatility and chemical character, which determine method of ...

Fast Analytical Techniques Based on Microextraction

2015
Abstract In this chapter, a set of useful microextraction techniques for the rapid analysis of a large number of persistent organic pollutants (POPs) from environmental samples was reviewed. These techniques included solid phase microextraction (SPME), liquid phase microextraction (LPME), stir bar sorptive extraction, extraction rod, thin-film ...

[Development of molecularly imprinted microextraction techniques].

Se pu = Chinese journal of chromatography, 2014
Microextraction techniques can extract efficiently the analytes from a sample matrix to the polymers or organic solvents of microvolume, and integrate sampling, extraction, concentration and injection into one single step. They have the advantages of simple, time-efficient and solvent-free.
