Definition of spectrometer in English: spectrometernounspɛkˈtrɒmɪtəspɛkˈtrɑmədər An apparatus used for recording and measuring spectra, especially as a method of analysis. Example sentencesExamples - The spectrometer provides the measure of the gold carat.
- Using a spectrometer, the transmittance spectrum is measured in a number of small regions in a stained tissue slide.
- The detector range of the array spectrometer is 200 to 875 nm, from ultraviolet into the near infrared.
- Research quickened in the 1980s as better measuring techniques emerged, notably gas chromatograph-mass spectrometers.
- The returning light would be detected by an imaging spectrometer to create a spectral image of the apple on a computer screen.
- We are collecting the water samples and analysing it with the atomic spectrometer.
- The energy reflected back can be analyzed by a spectrometer that researchers then interpret.
- One of the early uses of this was the development of the spectrometer for identification of elements.
- Experimentally, we compared the quantitative distribution of each pigment based on our proposed method with one measured using a spectrometer.
- The specimens were subjected to element analysis by an energy-dispersive spectrometer.
- Delta E is a scientific measure of color change calculated by using a color spectrometer which determines the amount of light refracted back to the instrument.
- It boasts ‘imaging infrared and ultraviolet spectrometers, a multi-color camera, a long-range telescopic camera, two particle spectrometers, a space-dust detector and a radio science experiment’.
- Both spectrometers were interfaced to computers for data analysis.
- The instruments on the orbiter include several cameras and spectrometers that work at different wavelengths: infrared, ultraviolet, visible and microwave.
- An X-ray spectrometer on board the rover performed 15 separate chemical analyses of the Martian soil, and identified large amounts of silicate minerals, suggesting that Mars had a similar geological history to the Earth.
- Working as miniature geologists, these robots will have miniature thermal emission spectrometers and an eye-height panoramic camera among their array of scientific instruments.
- It is likely that both the absorption spectrum and the emission spectrum are changed at high intensities with respect to the low-intensity spectra of DsRed recorded by conventional spectrometers.
- A spectrometer will measure the temperature of the atmosphere at various heights and pick out surface hot spots such as active volcanoes.
- He read the labels on the atomic spectrometer's controls and displays before taking a look into the sample chamber.
- The next Europa mission, planned for launch sometime after 2009, is expected to carry high-resolution spectrometers to map the surface and determine the mineralogical and organic composition of the surface ice.
Derivatives adjectivespɛktrəˈmɛtrɪkˌspɛktrəˈmɛtrɪk High-performance liquid chromatography methods gave results close to those found using mass spectrometric techniques. Example sentencesExamples - On the laboratory's first day of operation, a defective aircraft engine was identified through spectrometric wear metal analysis.
- This method has been validated against the gas chromatographic-mass spectrometric procedure in which the metabolites are independently quantified.
- In addition to numerous analytical vagaries, spectrometric systems are expensive to purchase and technically demanding to operate and maintain.
- Recovery of the single spots and subsequent mass spectrometric analysis revealed that the polypeptides in both spot clusters belonged to gelsolin.
nounspɛkˈtrɒmɪtriˈspɛkˈtrɑmətri The assay was validated directly by gas chromatography/mass spectrometry. Example sentencesExamples - Both samples are sent away for carbon dioxide isotope analysis by mass spectrometry (laboratories usually return the results within a few days).
- The first is examined using mass spectrometry, which knocks molecules apart and analyzes the debris.
- The charcoal tubes were desorbed with 1 ml of methylene chloride and analyzed by gas chromatography and mass spectrometry.
- The other way is to use gas chromatography/mass spectrometry to measure how much of the offending compounds are in pond water.
