Bir spektrometre, maddenin kimyasal bileşimini belirlemek için ışık kullanır. - A spectrometer uses light to identify the chemical composition of matter.
An optical instrument for measuring the absorption of light by chemical substances; typically it will plot a graph of absorption versus wavelength or frequency, and the patterns produced are used to identify the substances present, and their internal structure
An instrument for measuring spectra eg the electromagnetic spectrum Sometimes called a Ozone Hole-Ometer?? The ozone spectrophotometer (a device that compares wavelengths of light) that first alerted scientists to the ozone hole over Antarctica in the early 1980's, has changed very little since its invention by Gordon Dobson in 1927 (SOURCE: The Irish Times )
the portions of the NMR apparatus that actually produce the NMR phenomenon and acquire the signals, including the magnet, the probe, the RF circuitry, etc The spectrometer is controlled by the computer via the interface under the direction of the software
Device for detecting and analyzing wavelengths of electromagnetic radiation, commonly used for molecular spectroscopy; more broadly, any of various instruments in which an emission (as of electromagnetic radiation or particles) is spread out according to some property (as energy or mass) into a spectrum and measurements are made at points or regions along the spectrum. As used in traditional laboratory analysis, a spectrometer includes a radiation source and detection and analysis equipment. Emission spectrometers excite molecules of a sample to higher energy states and analyze the radiation emitted when they decay to the original energy state. Absorption spectrometers pass radiation of known wavelength through a sample, varying the wavelengths to produce a spectrum of results; the detector system reveals to what extent each wavelength is absorbed. Fourier-transform spectrometers resemble absorption spectrometers but use a broad band of radiation; a computer analyzes the output to find the absorption spectrum. Different designs allow study of various kinds of samples over many frequencies, at different temperatures or pressures, or in an electric or magnetic field. Mass spectrometers (see mass spectrometry) spread out the atomic or molecular components in a sample according to their masses and then detect the sorted components
