Alternative Sample Preparation Techniques in Gas Chromatographic - Mass Spectrometric Analysis of Urinary Androgenic Steroids

Sample 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 ...

Green Aspects of Sample Preparation – a Need for Solvent Reduction

Growing public concern over protecting our environment obligates chemists, including analytical chemists, to change chemical activity in such a way that it will be conducted in an environmentally friendly manner. The article provides an overview of green chemistry issues relating to sample preparation techniques, concentrating especially on the green advantages of so-called solventless sample p...

Sample Preparation Methods for Molecular Techniques for Drinking Water

OBJECTIVES: The goal of this project was to evaluate nucleic acid extraction techniques to detect different microbial pathogens (e.g., pathogenic viruses, bacteria, bacterial spores, and protozoan parasites) in drinking water using molecular techniques. While numerous nucleic acid extraction kits are commercially available, the composition of these kits is largely proprietary, making it difficu...
