Abstract: | 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-needle packings for microextraction
are discussed with their characteristic benefits, shortcomings and possible sampling modes. Special emphasis is placed on
methods providing full automation and solvent exclusion. In this context, in-tube extraction and the needle trap are discussed,
with an overview of current research on new sorbent materials, together with the requirements for more efficient method development. |
