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

X-ray fluorescence spectrometers (XRFs) 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. 

Atomic emission and optical emission spectrometers determine analyte concentration via a quantitative measurement of the optical emission from excited atoms.

Atomic absorption spectrometers (AA) use the absorption of light to measure the concentration of gas-phase atoms

Infrared (IR) spectrometers measure the wavelength and intensity of the absorption of infrared light by a sample

UV and visible spectrometers measure the amount of ultraviolet (UV) and visible light transmitted or absorbed by a sample placed in the spectrometer

Residual gas analyzers (Rags) identify the gases present in vacuum environments.

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

Raman spectrometers are used to measure the wavelength and intensity of inelastically scattered light from molecules. They can determine the chemical composition of a sample based on its wavelength and intensity

Specialty or proprietary products and accessories related to spectrometers

Fiber optic probes collect light or spectra from extreme environments inside reaction vessels at high temperatures or pressures. Product types include UV-Vis spectroscopy probes, Raman spectroscopy probes, and refractometry probes.

Fluorometers measure the amount of fluorescent radiation produced by a sample exposed to monochromatic radiation.

Flame photometers use atomic emission for the routine detection of metal salts, principally sodium (Na), potassium (K), lithium (Li) and calcium (Ca).

Wafer and thin film instrumentation includes quartz crystal microbalance (QCM) monitors, ellipsometers, RHEED systems, imaging stations, CD-SEMs, ion mills, and C-V systems specifically designed for wafer metrology or in-situ monitoring of thin film parameters during thin film or semiconductors wafer processing.

Polarimeters determine the amount of polarization of light.
