SPECTRO Analytical Instruments is a manufacturer of elemental analyzers using optical emission spectroscopy and x-ray fluorescence spectrometry. The company's headquarters are located in Kleve , Germany.
A spectrum analyzer is also used to determine, by direct observation, the bandwidth of a digital or analog signal. A spectrum analyzer interface is a device that connects to a wireless receiver or a personal computer to allow visual detection and analysis of electromagnetic signals over a defined band of frequencies.
Additionally, some specialized instruments, such as spectrophotometers built onto microscopes or telescopes, are single-beam instruments due to practicality. Historically, spectrophotometers use a monochromator containing a diffraction grating to produce the analytical spectrum. The grating can either be movable or fixed.
Spectroscopy is a branch of science concerned with the spectra of electromagnetic radiation as a function of its wavelength or frequency measured by spectrographic equipment, and other techniques, in order to obtain information concerning the structure and properties of matter. [4]
Byonic is a database search algorithm released in 2011 by Protein Metrics Inc. with original developments at PARC. [2] It searches MS/MS data from all types of instruments and internally employs the program Combyne, [3] which combines peptide identifications to produce protein scores and identification probabilities. CHIMERYS Proprietary
The ratio of the "sample spectrum" to the "background spectrum" is directly related to the sample's absorption spectrum. Accordingly, the technique of "Fourier-transform spectroscopy" can be used both for measuring emission spectra (for example, the emission spectrum of a star), and absorption spectra (for example, the absorption spectrum of a ...
Malvern Panalytical is a Spectris plc company. [6] The company is a manufacturer and supplier of laboratory analytical instruments. [7] [8] It has been influential in the development of the Malvern Correlator, [9] and it remains notable for its work in the advancement of particle sizing technology. [10]
The systematic attribution of spectra to chemical elements began in the 1860s with the work of German physicists Robert Bunsen and Gustav Kirchhoff, [30] who found that Fraunhofer lines correspond to emission spectral lines observed in laboratory light sources. This laid way for spectrochemical analysis in laboratory and astrophysical science.
