Fluorescence-Free Raman at 785nm
Raman spectroscopy is used around the globe for identification of unknowns, verification of raw materials, basic R&D, and process monitoring and control. The most commonly deployed technology is based on 785 nm lasers and detectors that leverage innovations from the telecommunications boom in the 1990s. However, this technology has been fundamentally limited by fluorescence interference that overpowers the Raman signal. The most common ways to overcome fluorescence have all had significant drawbacks around cost, safety and sample preparation – until now.
Developed for first responders to help identify unknowns in street narcotics, eXTRaction (XTR) technology uses advanced digital signal processing to separate Raman data from a background. With XTR, 785 nm Raman can be extended to difficult-to-analyze systems. In this webinar, Dr. Adam J. Hopkins and Elena Hagemann explain how XTR works and show different use cases for both qualitative and quantitative measurements, including biodiesel and polyurethane production.
