Innovative NIRaman Combi Fiber Probe

Art Photonics introduces a new combined fiber optic probe (NIRaman) enabling simultaneous real time measurements at the same point with Near-infrared spectroscopy (1000-2500nm) and Raman spectroscopy  (785 – 1000nm) methods.    The wavelength ranges of both channels are separated but both channels can work simultaneously.   NIRaman Combi fiber probe, which not only significantly expands the capabilities of the well-known FlexiSpec® product line, but also opens up new opportunities for the development of various Combi-probes.

Raman and NIR spectra contain qualitative and quantitative information on the chemical composition and physical properties of the substance.  Both are able to supply critical product and process information during production. The probe is compatible with all Raman and NIR spectrometers and their data fusion enables to enhance accuracy and sensitivity of process-control in-line. Flexible and robust fiber probe design allows to use them in harsh environment or a broad variety of industrial applications, including, but not limited to: 

• Reaction monitoring in real time/ in situ
• Process Analytical Technologies (PAT) in line
• Analytical characterization in science and for environment monitoring
• Remote media analysis in pharma

One example is raw materials identification (RMID).  It is highly desired to identify raw materials in a fast and non-destructive manner in quality control  process in pharmaceutical, food and chemical industries.   Near-infrared spectroscopy is a technique that uses light between 800nm and 2500nm (12500 to 4000cm⁻1 ) to excite certain molecular vibrations.  Also, absorption intensity is lower than in the mid-infrared region, which allows for deeper penetration of the source light into the material.   On the other hand, Raman spectroscopy relies on the non-elastic scattering of photons from a laser source.  As the photons from the laser interact with the material, a few are absorbed. The energy from these photons is partially absorbed and the remaining energy is re-emitted as scattered light at a different frequency. The spectrum generated by a Raman instrument generally has sharper and better resolved peaks than NIR.  The combination of two channels offers excellent capability of raw material identification.
