DIY Extended Range (Concatenation) Raman
Our DIY Extended Range Raman system provides the highest level of fluorescence rejection. Combined with wide range spectral coverage and excellent spectral resolution Raman spectral coverage by utilizing an 860 nm/1064 nm laser combination, this system will provide results when a more conventional 785 nm Raman system falls short.
Concatenation Raman System
This system is ideal for the many of the more challenging applications for Raman analysis without sacrificing data quality, spectral coverage, or resolution.
Included:
1. Research-grade Sol HT 1.4 spectrometer, providing extended Raman coverage from 200 to 4600 cm-1, while providing a resolution of 10 cm-1.
2. Configurable Raman Probe designed for dual-wavelength operation in a single probe body.
3. Turn-Key Laser, dual-wavelength system
Applications for Raman Concatenation
When samples have strong fluorescence, Raman concatenation allows for shifting the fingerprint excitation laser to longer wavelengths, even 1064 nm, and still allows for measuring the Raman stretch region, enabling the measurement of aliphatic and aromatic C-H stretch differences, compounds with N-H stretches, and even the elusive water O-H stretch which is extends out to beyond 3600 nm.
Petroleum
Biodiesel & fuel blends
Polymers
Polymerization reactions with structural changes visible in both the Fingerprint Region and Stretch Region, such as Bakelite formation and epoxy resins.
Environmental
Plant-based monitoring, where the Fingerprint Region provides data on the structural compounds and carotenoids, and the Stretch Region allows simultaneous monitoring of water content and plant stress. Below is an example of a typical spectrum of a plant sample.
Raman Concatenation Brochure
Raman Concatenation is an exciting new technique, and it involves sequentially collecting Raman spectra from two NIR lasers with one Raman spectrometer and one Raman probe. It enables fluorescence free spectra of the fingerprint and stretching region with increased sensitivity and discrimination.
