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.
متن کاملSampling 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...
متن کاملVibrating Sample Holder for Xrd Analysis with Minimal Sample Preparation
A new approach to sample handling for powder X-ray diffraction analysis is presented that allows characterization of poorly prepared samples. The technique relies on vibrations generated in a sample holder to create movement of the powdered sample in the absence of macroscopic movement of the sample holder itself. The major benefits over conventional sample handling strategies are: 1) the abili...

متن کاملA sample preparation method for microbiological analysis of seeds
There have been several outbreaks of food poisoning linked to the consumption of raw sprouts. The two most common pathogens associated with sprout consumption are Salmonella spp and verocyto-toxin producing Escherichia coli. During sprouting the warm, humid and nutrient rich conditions are ideal for bacterial growth. Pathogenic bacteria can infect seeds at very low numbers only to grow to dange...
