On-line and In-line Measurement

A scientific approach to industrial particle processing is based on the development of means of characterizing particle systems. The present state of awareness mainly relies on laboratory instruments treating samples taken from process plant and analyzed off-line. This allows process investigation, checking specifications of raw materials and final products. However, recent developments in on-line measurements offer the possibility of following process dynamics, getting better and more rapid control, and eliminating questions about the statistical significance of quality control based on sampling. Papers are invited that describe on-line instrumentation for determining the characteristics of particle systems in-situ in process plant and that describe how in-line measurements from such instruments lead to process improvements.
