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.

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

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

Analytical laboratory services detect, classify and/or assay chemical, material, biological, geological and environmental samples.

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

Mass spectrometers separate ions by their mass-to-charge (m/z) ratios.
