Equipment | Chemical Analysis |Spectrometers


Generally used to identify the composition of a sample, spectrometers gauge characteristics of light over a particular part of electromagnetic spectrum. These devices send a beam of light through a diffraction grating, which divides the light into component wavelengths. The grating is adjusted to ensure that a particular wavelength hits the sample. From here, a detector gauges the quantity of light that passes through the sample and the quantity of light that is absorbed by the sample. Computer software then analyzes this information based on the amount of pixels in the spectrometer's detector and the linear distribution of the diffraction grating, enabling the data to be plotted as a function of wavelength over a provided spectral range. This information can then be used and interpreted for innumerable spectroscopic applications.
