Why Raman Spectrometer?
Raman scattering and infrared absorption spectroscopy is a spectroscopic technique complementary measurement techniques. Raman spectroscopy method has the ratio of the number of types of infrared (mid-IR) spectroscopy or near-infrared (near-IR) spectroscopy superior characteristics, comprising:
Rarely require sample preparation.
Water is a weak scatterer, so, in the measurement solution, no special accessories is needed.
Water vapor and carbon dioxide are very weak scattering body, so no special purification.
Inexpensive glass stage, the situation in most would have been sufficient for holding a sample carrier.
Optical fiber can be used to guide light, some special occasions, you can do remote analysis, the distance can be up to 100 meters.
Because most of the materials have been based on the measurement, and modeling the Raman bands can be easily related to a certain chemical structure.
Raman spectroscopy in the infrared spectrum is "cleaner", because the Raman band is quite narrow, usually attached together band harmonic or weak.
Usually in the range of the standard spectra 400-1 wave number or less, so that Raman spectroscopy applied to both organic and inorganic substances analyzed.
Raman spectroscopy can be used to measure the symmetry bond, which is red spectrometer weaknesses (eg -SS -, - CS -, - C = C-)
ACTTR is the most aggressive & the most professional instrument of spectrometer distributor, agent, reseller, in Taiwan.
