Reference Sampling for Process Analytical Technologies (PAT) - Theory of Sampling (TOS)

Representative sampling forms a critical success factor for PAT in general as well as for any spectroscopic approaches. Many instrumental analytical methods (X) are based on "analysis by proxy", for which the representativity of reference data (Y) is critical w.r.t. underlying multivariate calibrations. Although the Theory of Sampling (TOS) has been known for 25-50 years, it is still only little appreciated and implemented in today's process analytical chemistry, even though sampling errors form the dominant part of what is termed "measurement errors" - typically is 100 X (or more) larger the analytical error s.s. There is no simple way out of the need for representative primary reference sampling - and the situation can not be remedied by neither statistics, chemometric data analysis or by any other type of a posteori "corrections". This introductory lecture presents a theoretical as well as practical framework of seven sampling unit operations (TOS) with which to approach all types of sampling issues in the field or plant, in industry or the laboratory for PAT purposes.
