Spectrometers

Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available. Performance specifications for spectrometers include: spectral range, spectral resolution, mass range, mass resolution, and mass accuracy. Spectral range is the dispersion of the grating across the linear array, or the “size” of the spectra on the array. Spectral resolution is the width of an analytical peak at half its height as measured in nanometers (nm). This value indicates the spectrometer’s ability to separate two overlapping peaks. Spectral accuracy is the agreement between a mean measured value and a true or accepted value as quantified by error. Mass range is a measurement of atomic mass that is expressed in atomic mass units (amu) or Daltons (Da). Mass resolution is the ratio of the mass divided by the change in mass over the area of two peaks.  

There are many different types of spectrometers. UV and visible spectrometers measure the amount of ultraviolet (UV) and visible light transmitted or absorbed by a sample placed in the spectrometer. Infrared (IR) spectrometers measure the wavelength and intensity of the absorption of infrared light by a sample. Atomic absorption (AA) spectrometers use the absorption of light to measure the concentration of gas-phase atoms. Atomic emission (AA) and optical emission (OE) spectrometers determine analyte concentration via a quantitative measurement of the optical emission from excited atoms. Raman spectrometers are used to measure the wavelength and intensity of inelastically scattered light from molecules. X-ray fluorescence spectrometers (XRF) use a spectroscopic technique that is commonly used with solids, in which X-rays are used to excite a sample and generate secondary X-rays.  Mass spectrometers separate ions by their mass-to-charge (m/z) ratios. They are used to identify compounds by the mass of one or more elements in the compound. They are also used to determine the isotopic composition of one or more elements in a compound.
