MONITORING OF AN INDUSTRIAL-PROCESS WITH REMOTE RAMAN-SPECTROSCOPY

In recent years, the application of spectroscopic methods has become widespread in industry because of the advantages of the use of optical fibres for remote analyses [1-3]. One of the most developed techniques is certainly near-infrared absorption [4, 5] coupled with chemometrics [6]. However, one of ifs limitations is the use of a 1-D detector, so that multipoint analyses have to be made sequentially In most cases, this could be very limiting whilst the use of a 2-D defector as encountered in Raman spectroscopy is of great interest [7, 8].
