Paper Abstract

Infrared analysers for measuring the composition of simple flowing gas streams on chemical plant have been available for more than 40 years. For almost as long, infrared spectrometers have been used in research laboratories to measure the composition of complex liquid and solid samples. Instrument performance has been improved, new sampling methods have been devised and mathematical procedures developed whereby measurements can now be made in plant laboratories by plant operators on complex gas and condensed phase products with sufficient precision zor specification testing and sufficient speed to permit composition trends to be followed. Recently, IR probes have been developed which permit remote measurements on liquids inside chemical plant vessels, and these sensors may well produce information of sufficient quality to permit real plant control. It is the object of this paper to follow these developments and assess the present position.
