Sample Preparation Techniques for Microhistological Analysis

Microextraction Techniques as a Sample Preparation Step for Metal Analysis

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 ...

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...

Sample Preparation for Bioanalytical and Pharmaceutical Analysis.

Biological and pharmaceutical samples represent formidable challenges in sample preparation that hold important consequences for bioanalysis and genotoxic impurity quantification. This Feature will emphasize significant advances toward the development of rapid, sensitive, and selective sample preparation methods.

Sampling and sample preparation for food analysis

The term “food” refers to the broad range of edible materials that comprise the essential body nutrients required for life and growth, such as proteins, carbohydrates, fats, vitamins, or minerals. Foodstuffs are described variously as “lic&id” or “solid”, and “wet” or “dry”, depending on the amounts of water and fat they contain. Samples of plant origin are classified for analytical purposes as...
