Raman analyzer measures online.

Kaiser's RamanRxn2 1000 Raman analyzer provides the fluorescence rejection of a FT-Raman spectrometer with the ease of fiberoptic interfacing of a dispersive Raman analyzer. Using 1000-nm excitation is a compromise between fluorescence rejection and detection sensitivity. For non-Raman spectroscopists the observation of any level of fluorescence background can lead to a desire to move to a different excitation wavelength. However, it is often possible to remove the background during a data analysis step leaving a residual spectrum of high enough signal-to-noise ratio to allow quantitative analysis. While 785-nm excitation remains a universal wavelength for petrochemical and pharmaceutical applications, some applications such as early stage "dirty" crystallization exhibit fluorescence too intense to be addressed with 785-nm excitation. For these, the analyzer provides an effective route for in situ monitoring. Kaiser Optical Systems, Inc. www.kosi.com, 734-665-8083
