Raman spectroscopy provides information about molecular vibrations that can be used for sample identification and quantitation. The technique involves shining a monochromatic light source (i.e. laser) on a sample and detecting the scattered light. The majority of the scattered light is of the same frequency as the excitation source; this is known as Rayleigh or elastic scattering. A very small amount of the scattered light (ca. 10-5% of the incident light intensity) is shifted in energy from the laser frequency due to interactions between the incident electromagnetic waves and the vibrational energy levels of the molecules in the sample. Plotting the intensity of this "shifted" light versus frequency results in a Raman spectrum of the sample.

 

Due to its sensitivity and non-destructive nature, Raman spectroscopy is now used in many applications across the field of chemistry, biology, pharmacology, pharmaceuticals, materials science, and failure analysis. Some applications of Raman spectroscopy in nanotechnology are as follows:

  • Identification and separation of some organic and inorganic compounds.
  • Determining chemical composition of compounds.
  • Analysis of nanoparticles.

Of the benefits of array technology is fast scanning and ability to scan the whole wavelengths in the range of 150-4500 cm-1 in less than one second, which can be used for fast chemical reactions, etc. Details of technical specifications are presented in the following Table.

Nanoparticles have optical properties that are sensitive to size, shape, concentration, agglomeration state, and refractive index near the nanoparticle surface, which makes Raman spectroscopy a valuable tool for identifying, characterizing, and studying these materials. Therefore, using a Raman spectrometer, each nanoparticle can be characterized.

  • To turn off the device, first turn off the shutter and lamp; wait about 30 seconds to fan being off. Then turn off the device. To avoid electrical fluctuations and damage to the device, it is better to use UPS.
  • Spectrometer and sample container must be kept clean. Furthermore, device should be cleaned with soft and damp cloth. Be careful not to allow any liquid goes into the device because it may damage the device and be dangerous.
  • For more details on how to use the device, refer to the device catalog and user guide.
  • At the end of the work, remove the specimens from the sample cell.
  • Use proper methods for sample disposal.
  • Make sure the device is off.
  • The device is packed with accessories, including software CD, USB and electrical cable, calibration sheet and guaranty sheet.
