Analytical methods

Abstract

Analytical chemistry has traditionally been associated with basic research but in the past few years it has become a key support area in many industries. In the cosmetic and personal-care product industries it is used to support the commercial development and application of new ingredients, to ensure that specifications are met, to confirm the quality of manufactured products and to ensure that processes are operating correctly. Outside of the industrial environment analytical methods are regularly employed by enforcement and regulatory authorities to ensure that products conform to legal standards, and are safe and accurately described. Increasing demand for the determination of analytes at very low levels and more rapid results to match production levels has led to the development of a wide range of sensitive techniques, many capable of automation and multicomponent analysis. Despite the ease with which many of these techniques can be applied, the analytical chemist continues to play a key role in selecting the most appropriate method, managing the data, interpreting the results and commenting on their significance to other staff.
