Powerful in Process Applications
Raman-spectroscopy generates very characteristic spectra, which are due to substance-specific molecular vibrations – the so-called “molecular fingerprint.”
Applications of Raman spectroscopy are well-established, e.g., pharmaceutical production, biotechnology, food and agricultural industries, or petrochemistry.
Typical applications for qualitative analyses are the inspection of raw materials in incoming goods inspection and applications in areas where e.g., unknown or critical substances need to be identified.
Quantitative analyses utilizing Raman spectroscopy are of increasing importance in the manufacturing industry for online or inline process control. The specificity of spectra, in conjunction with standard chemometric methods, enables selected monitoring, control, and optimization of numerous production processes.
For safe operation, all installations can be executed according to laser class 1. Intrinsically safe variants with ATEX type certification enable uncomplicated to use in hazardous areas.
Raman spectroscopy reveals undreamt-of application possibilities – for your process as well as in the laboratory.
