In the chemistry, pharmaceutical, materials testing, and petrochemical industries, the ability to quickly analyze and identify a substance is key. One solution is to use a Raman spectrometer. By taking advantage of the scattering of laser light hitting a sample, a Raman spectrometer can read the subtle energy shift in the scattered light caused by the vibration of the substance undergoing analysis. Raman spectrometers typically employ diode or gas lasers of 532 or 785 nm. For applications like forensics, where samples are often contaminated, some Raman spectrometers offer wavelengths of 1064 to filter fluorescence at the cost of overall sensitivity.
Considerations for purchasing a Raman spectrometer
Detectors for Raman spectrometers include CCD arrays, InGaAs, or Ge types. Some Raman spectrometer systems are coupled with high-end microscopes for micro molecular analysis.
