Spectrometry, Mass, Secondary Ion - 새창 A mass-spectrometric technique that is used for microscopic chemical analysis. A beam of primary ions with an energy of 5-20 kiloelectronvolts (keV) bombards a small spot on the surface of the sample under ultra-high vacuum conditions. Positive and negative secondary ions sputtered from the surface are analyzed in a mass spectrometer in regards to their mass-to-charge ratio. Digital imaging can be generated from the secondary ion beams and their intensity can be measured. Ionic images can be correlated with images from light or other microscopy providing useful tools in the study of molecular and drug actions.
Synonyms : Secondary Ion Mass Spectroscopy, Secondary Ion Mass Spectroscopy Microscopy
Spectrometry, X-Ray Emission - 새창 The analysis of the spectrum of fluorescent X-RAYS, i.e. X-rays emitted after bombarding matter with high energy particles such as PROTONS; ELECTRONS; or higher energy X-rays. The identification and quantitation of ELEMENTS by this technique is based on the fact that the wavelength and intensity of the fluorescent X-rays are characteristic of specific elements and the concentration of the elements in the matter being analyzed.

Spectrophotometry - 새창 The art or process of comparing photometrically the relative intensities of the light in different parts of the spectrum.
Synonyms :
Spectrophotometry, Atomic - 새창 Spectrophotometric techniques in which the samples are examined in the form of atoms based on their unique energy levels for ELECTRONS. They are used to analyze TRACE ELEMENTS, such as ALUMINUM; ARSENIC; BERYLLIUM; CALCIUM; COPPER; IRON; LEAD; and LITHIUM.
