Abstract
The flow characteristics of an on-line analyser were measured using a
stimulus response technique. The analyser was developed for
monitoring homogeneous catalyst concentrations in a non-aqueous
solution and it was considered important to limit dispersion effects
between sample injection and measuring points. Various tube lengths
between these points were used and the system was operated over a
range of flow rates. The detectors employed were electrochemical in
nature and of two different designs.
The residence time distributions of the system were determined
experimentally and analysed by the method of moments and frequency
techniques. As expected dispersion of the sample decreased as tube
length decreased and flow rate increased.
An attempt was made to fit the experimental results to the axially
dispersed plug flow model. This was only successful over a limited range
of the variables.
