Spectrometry, Fluorescence - 새창 Measurement of the intensity and quality of fluorescence.
Synonyms : Fluorescence Spectrometry, Spectrophotometry, Fluorescence, Spectroscopy, Fluorescence
Spectrometry, Gamma - 새창 Determination of the energy distribution of gamma rays emitted by nuclei. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Synonyms : Gamma Spectrometry, Spectrophotometry, Gamma
Spectrometry, Mass, Electrospray Ionization - 새창 A mass spectrometry technique used for analysis of nonvolatile compounds such as proteins and macromolecules. The technique involves preparing electrically charged droplets from analyte molecules dissolved in solvent. The electrically charged droplets enter a vacuum chamber where the solvent is evaporated. Evaporation of solvent reduces the droplet size, thereby increasing the coulombic repulsion within the droplet. As the charged droplets get smaller, the excess charge within them causes them to disintegrate and release analyte molecules. The volatilized analyte molecules are then analyzed by mass spectrometry.
Synonyms : Mass Spectrometry, ESI, Spectrometry, ESI Mass
Spectrometry, Mass, Fast Atom Bombardment - 새창 A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information.

Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization - 새창 A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis.
