Specialty Spectrometers and Accessories

Specialty spectrometers and accessories are specialty or proprietary products and accessories related to spectrometers, analytical instruments that are used measure the amount of dispersion of a property such as mass or energy. Like other types of spectrometers, specialty spectrometers are used to determine chemical composition and to perform electromagnetic radiation analysis by measuring light intensity across the visible, ultraviolet (UV), and infrared (IR) spectrums. A specialty spectrometer can be built using optical detectors such as charged coupled devices (CCD) or photo diode arrays, or fiber optics.

Specialty spectrometers and accessories are often application-specific and differ in terms of performance specifications such as wavelength range, optical resolution, sensitivity or absorption, and data capture speed. Products used in thin film analysis are different from those used in biomedical applications, or for monitoring inline process control. Some specialty spectrometers are used in medical imaging applications. For example, nuclear magnetic resonance (NMR) spectroscopy is used to determine physical and chemical information about a specific molecule, typically organic compounds. Resonance spectroscopy is based on the magnetic property of an atom's nucleus and its response to an electromagnetic field. This is the technique used in magnetic resonance imaging (MRI).

Many other types of specialty spectrometers are available. Secondary ion mass spectrometry (SIMS) is a technique for analyzing the surface of a thin film test sample. An ion mass spectrometer is used to analyze the particles emitted by an object after 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 with an electron beam. Auger electron energies are tabulated based on the Auger effect or process.

Suppliers of specialty spectrometers are located across the United States and around the world. They conform to various quality standards and regulatory requirements.
