摘要

The majority of low level concentration measurements, whether for process control, product quality monitoring, or emissions monitoring, are based on extractive analysis of a gas or liquid sample. Often the chemical species to be measured are reactive, and the physical distance between the sample point and the analyzer shelter is significant. In such cases, the ability of the sample system to reliably transport the species of interest in a timely manner is critical to such measurements. Improper design of the system to meet such requirements results in unnecessary lag time and slow responding systems or makes accurate process gas analysis impossible. To properly employ extractive analytical systems, factors such as response lag and sample loss due to adsorption and chemical reactions on the surfaces of the flow path must be considered and addressed. The theoretical and practical analysis of such factors and design guidelines will be presented.
