New Techniques for Sample Preparation in Analytical Chemistry Microextraction in Packed Syringe (MEPS) and Methacrylate Based Monolithic Pipette Tips
Sample preparation is often a bottleneck in systems for chemical analysis. The aim of this work was to investigate and develop new techniques to address some of the shortcomings of current sample preparation methods. The goal has been to provide full automation, on-line coupling to detection systems, short sample preparation times and high-throughput. In this work a new technique for sample pre...
متن کاملMicroextraction by Packed Sorbent (MEPS) and Solid-Phase Microextraction (SPME) as Sample Preparation Procedures for the Metabolomic Profiling of Urine
For a long time, sample preparation was unrecognized as a critical issue in the analytical methodology, thus limiting the performance that could be achieved. However, the improvement of microextraction techniques, particularly microextraction by packed sorbent (MEPS) and solid-phase microextraction (SPME), completely modified this scenario by introducing unprecedented control over this process....
متن کاملSample preparation using liquid membrane extraction techniques
A brief review is given of membrane extraction techniques that are seen as suitable for the extraction of various chemicals in water samples. Membrane-based extraction methods have now gained popularity as methods of choice in the extraction of both ionisable and non-ionisable molecules from different samples. The main attractive features for these techniques include the use of minimal organic ...

15 صفحه اولSample preparation and processing
Errors made during the sample preparative process contribute significantly to the total analytical error of immunoassays. Reduction in the magnitude of these errors have been made by improvements in the manualfluid handling systems and mechanization of the individual steps in the process. The mechanization has been stimulated by developments in both computing hardware and software. A laboratory...
