Fluorescence is the phenomenon where molecules/ atoms absorb light within their absorption band and then emit this light at longer wavelengths within their emission band. This phenomenon can be used to identify, quantify, and observe chemical activity, and it is a popular method due to its high levels of sensitivity, simplicity, and specificity.

Fluorescence spectroscopy is a spectroscopy method used to analyze the fluorescence properties of a sample by determining the concentration of an analyte in a sample. This technique is widely used for measuring compounds in a solution, and it is a relatively easy method to perform. In this technique, a light of a specific wavelength band is passed through a solution, which emits the light towards a filter and into a detector for measurement. The amount of light that is absorbed by the sample (excitation spectrum) and the amount of light that is emitted by the sample (emission spectrum) can be quantified. The concentration levels of the analyte compound within the solution can be determined as these levels are directly proportional to the emission spectrum.

Laser induced fluorescence spectroscopy is a type of spectroscopy where the sample is illuminated with a laser causing molecules in the sample to be electronically excited. The photons emitted as a result of the decay of the molecules back down to the ground state are measured.

Fluorescence Spectroscopy:

  • Quantitative analysis of small amounts of many organic and inorganic compounds. Accordingly, it can be used to analyze chemical, biochemical, pharmaceutical, etc.

Laser Induced Fluorescence Spectroscopy:

  • Detecting molecules and atoms.
  • Measuring species concentrations and energy-level population distributions.
  • Probing energy transfer processes in molecules and atoms.

The Fluorescence Spectrometers provided by this company are designed and produced in two different models. 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 fluorescence spectroscopy a valuable tool for identifying, characterizing, and studying these materials. Therefore, using a fluorescence spectrometer, each nanoparticle in low volume can be identified and measured.

  • 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.
  • At the end of the work to prevent contamination, cover the optical fibers and avoid excessive bending of them.
  • After finishing the work, thoroughly clean the fluorescence cell and keep it in a suitable place.
  • 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.
  • Avoid Exposure to the Laser Radiation (in case of using laser induced fluorescence spectrometer).
  • The device is packed with accessories, including software CD, USB and electrical cable, calibration sheet and guaranty sheet.
