...it is bombarded with a stream of ions or charged particles. Electron auger spectroscopy is also used to analyze surface composition of materials. Auger electron spectroscopy (AES) measures the energies of Auger electrons, which are created by bombarding the sample... Learn More

There are many different types of optical calibration standards. Categories include lamp calibration standards, spectroscopy standards, and photometer standards. There are two basic types of lamp calibration standards: calibrated irradiance sources... Learn More

...temperature atomization sources provide sufficient energy to promote the atoms into high energy levels. The atoms decay back to lower levels by emitting light. Since the transitions are between distinct atomic energy levels, the emission lines in the spectra... Search by Specification | Learn More

...and mechanical testing. Analytical laboratory services may also use various microscopy and metallography techniques and perform nondestructive testing (NDT), property testing, opacity testing, optical emission spectroscopy, scanning electron... Search by Specification | Learn More

...of very weak signals, is a photo emissive device in which the absorption of a photon results in the emission of an electron. These detectors work by amplifying the electrons generated by a photo cathode exposed to a photon flux. A diode array... Search by Specification | Learn More

...spectometer measure the vibrational energies of the molecules in a sample. Infrared spectroscopy or IR spectroscopy measures the absorption of light of certain energies that correspond to the vibrational energy of the molecule. Since Raman scattering... Learn More

...infrared light is energetic enough to excite molecular vibrations to higher energy levels. These vibrations, which are caused by changes to a molecule’s dipole moment, occur only at those frequencies where the molecule absorbs infrared light... Search by Specification | Learn More

...that are difficult to vaporize or ionize. In fast atom bombardment (FAB) a high-energy beam of neutral atoms, typically Xe or Ar, strikes a solid or low-vapor-pressure liquid sample causing desorption and ionization. It is used for large biological... Search by Specification | Learn More

...a solid or liquid, is vaporized in a flame or in a graphite furnace with a temperature of 1000° - l 200° K. Atoms absorb ultraviolet or visible light and achieve higher energy levels. Absorption amounts determine the analyte concentration... Search by Specification | Learn More

Monochromators are optical subassemblies used to isolate narrow portions of a light spectrum. They accept polychromatic input from a lamp or laser, and outputs monochromatic light. Learn More
