Sampling and Sample Preparation

Abstract

Sampling and sample preparation include the treatment of the theory, the methodology of sampling in all physical phases, and the theory of sample preparation for all major extraction techniques. The analytes in food sample are randomly distributed and variability. The analytical results depend on the type of sample and on the sample preparation techniques (handling, filtering of water, sieving of soils/sediments, drying, homogenizing). So, the highest-quality data are obtained as well as analytical techniques and methods offer excellent performance in achieving high sensitivity, selectivity, and identification capabilities for a wide range of contaminants.
