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

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

Time and frequency standards can include cesium or rubidium atomic clocks, quartz oscillators, hydrogen masers and other master clocks. Time reference sources are used in networks & telecommunications, observatories, utilities and navigation (GPS

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

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. 

Color and appearance instruments are used to measure the properties of paints and coatings including color, gloss, haze and transparency.

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.

Specialty microscopes are designed for specific applications such as metallurgy or gemology. They use specialized techniques or technologies such as acoustics to produce magnification.

Optical calibration standards are used to calibrate the optical properties of optical detectors and instruments.

Photometers produce electrical signals, which correspond to radiant flux energy, for a series of discrete wavelength intervals. They are used to measure wavelengths of light spectra and optical or atomic emissions

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

Microscopes are instruments that produce magnified images of small objects

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

Grinding wheels are used for metal removal, dimensioning, and finishing. They consist of an integral shank, pin, shaft, or mandrel that drives a mounted wheel or blades.
