General Principles of Good Sampling Practice

Sampling is the first and arguably most important step in the analytical process. Obtaining representative and reliable samples of any bulk material being analyzed is of the utmost importance. This book brings together the broader principles of sampling applicable to a wide variety of situations. Prepared under the Department of Trade and Industry’s Valid Analytical Measurement (VAM) Initiative, it covers solid, liquid and gas samples, with examples of some of the equipment used. The book is based on an intensive literature survey covering a wide range of materials. It offers guidance on particle size reduction of solids and examines requirements for suitable containers and storage prior to analysis. The text places particular emphasis on the preparation of sampling plans. Checklists ensure that coverage is comprehensive. Additionally, various safety aspects are considered and some theory is addressed.
