Sample preparation , in analytical chemistry , the processes in which a representative piece of material is extracted from a larger amount and readied for analysis. Sampling and sample preparation have a unique meaning and special importance when applied to the field of analytical chemistry. Analytical chemistry in all its diverse forms can be looked upon as a multistep endeavour with the measurement phase but one link near the end of a chain of operations. That chain begins with sampling, an essential process that underlies all subsequent work and imparts relevance to what would otherwise be a meaningless exercise.
Sampling and Sample Preparation
Handbook of Food Chemistry pp Cite as. 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. 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.

Comprehensive Sampling and Sample Preparation is a complete treatment of the theory and methodology of sampling in all physical phases and the theory of sample preparation for all major extraction techniques. It is the perfect starting point for researchers and students to design and implement their experiments and support those experiments with quality-reviewed background information. In its four volumes, fundamentals of sampling and sample preparation are reinforced through broad and detailed sections dealing with Biological and Medical, Environmental and Forensic, and Food and Beverage applications. The contributions are organized to reflect the way in which analytical chemists approach a problem. It is intended for a broad audience of analytical chemists, both educators and practitioners of the art and can assist in the preparation of courses as well in the selection of sampling and sample preparation techniques to address the challenges at hand. Above all, it is designed to be helpful in learning more about these topics, as well as to encourage an interest in sampling and sample preparation by outlining the present practice of the technology and by indicating research opportunities.
This kit contains a tools and materials for gas, liquid, and solid sampling. For solid sampling, a hand press is included for making KBr pellets. Variable pathlength liquid demountable cell is included for the analysis of liquid samples.
