Molecular Analyzers Raman


TSI's Raman Spectrometers deliver laboratory-grade measurements to its complete product line including "good," "better," and "best" solutions in handheld, portable, bench top and installed process control instruments. High spectral resolution, fast measurements, and consistent instrument performance offer better solutions for rapid material identification applications including: incoming raw material identification, counterfeit identification, polymer & plastics, gemology, mineralogy, food safety, and chemical research.

TSI | Chemlogix raman spectrometer instrument suite

The TSI | ChemLogix Raman spectrometer products are built around two types of solid state laser systems, frequency-doubled diode-pumped Nd:YAG lasers and semi-conductor (diode) lasers. Both of these laser types are very stable, with useful lifetimes in excess of 10,000 hours. Spectrometers and detectors are integrated in-house and carefully optimized. Our systems offer unusually high dynamic range and systems are fiber-coupled to eliminate alignment issues.

Quality components and precision assembly yield miniaturized Raman systems that mitigate fluorescence issues well, have high signal-to-noise characteristics, and are easy-to-use. This means that non-technical operators can take fast and accurate measurements.

TSI's Raman spectroscopy line includes handheld and bench-top instruments. The handheld Raman spectrometers are ideal for pharmaceutical and homeland defense applications. For greater sensitivity, we offer bench-top and portable devices and several grades of Raman microscopes. Two specialty instruments are available for Raman measurements in gases. We can also customize Raman systems to better suit process control environment. 


Our high-performance, easy-to-use Raman spectrometers meet your needs for:

  • affordability
  • high sensitivity
  • fast material identification with short sample times
  • repeatable measurements instrument-to-instrument
  • a transferable database across all platforms, and
  • excellent fluorescence rejection

For sensitivity, TSI Raman Spectrometers compare with high-end, confocal Raman spectrometers, but at a much lower price point.
