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

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

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

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

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

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

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

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. 

Material testing services test, analyze, and certify a wide range of materials for purity, chemical compatibility, and environmental impact.

Polymer test equipment includes melt flow indexers, extrusiometers, and other specialized instruments for determining the processability and properties of plastics and elastomer materials.

Liquid filtration elements are used to remove impurities from liquids. They are used in water treatment systems and fluid processing applications.

Foams and foam materials are industrial products made from low density elastomers, plastics, and other materials with various structures and porosities.
