How much does a portable Raman spectrometer cost?
Commercially available Raman spectrometers cost a minimum of $12,000 U.S. and are thus unaffordable by most schools and colleges.
How does Raman instrument work?
Raman spectroscopy works by shining a monochromatic light source—usually a laser—onto a sample and detecting the scattered light. Plotting the intensity of the shifted light against the frequency produces a Raman spectrum of the sample.
What is handheld Raman?
A portable Raman spectrometer is a hand held tool used to identify or verify the components of a sample. The portable Raman spectrometer collects light emitted from a sample after it is hit with a laser and with the collected light creates a spectrum that is used to identify the material .
What are the types of Raman?
There are now more than 25 different types of known Raman spectroscopy techniques, such as spontaneous Raman, hyper-Raman scattering, Fourier transform Raman scattering [5], Raman-induced Kerr effect spectroscopy [6] and stimulated/coherent Raman scattering [1].
What is the difference between Raman and FTIR?
The key difference between FTIR and Raman spectroscopy is that FTIR technique measures how much light is remaining from the original light from the light source, whereas Raman spectroscopy measures the energy that scatters after being excited by a laser.
Where are spectrometers used?
Uses of Spectrometer
- Monitoring dissolved oxygen content in freshwater and marine ecosystems.
- Studying spectral emission lines of distant galaxies.
- Characterization of proteins.
- Space exploration.
- Respiratory gas analysis in hospitals.
How does a portable Raman spectrometer work?
Using a high sensitivity InGaAs array detector with deep TE cooling and high dynamic range, this portable Raman spectrometer delivers a high signal to noise ratio without inducing auto-fluorescence, making it possible to measure a wide range of biological samples.
What can I do with the I-Raman plus?
