Abstract:

A mathematical relationship between the real concentration and the measured concentration of a material in a stream flowing into a sampling chamber is derived. It shows how the flow rate and the size of the sampling chamber affect the determination of the measured concentration. Graphical and numercal representations of this relationship are presented. The relationship can be used to predict possible errors involved in sampling. It also can be used by designers of processes, equipment, and instruments to size sample or mixing chambers when the flow rate and the variation in concentrations are known. Author
