Axiom Analytical has installed its first large-scale Raman immersion probe for chemical batch process monitoring, at a chemical manufacturing plant.
The three-metre-long probe enables access from the top of a large-scale batch reaction vessel and allows Raman spectroscopy to be used for process monitoring in a range of chemical and pharmaceutical processing applications.
Many reaction vessels are glass-lined or employ heating coils, eliminating the possibility of side-entry into the vessel and the use of shorter Raman probes.
The new probe overcomes these obstacles and provides optical efficiency with its lightguide.
Raman Spectroscopy is suitable for process monitoring because it combines the high degree of specificity characteristic of mid-IR spectroscopy with visible and near-IR optical components.
It can be used with efficient fused silica optical fibres for transmission of optical signals between the probe and a remote Raman spectrometer.
