| spectrometry, mass, matrix-assisted laser desorption-ionization | 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.

| spectrometry, mass, fast atom bombardment | 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. (12 Dec 1998) |
| spectrometry, mass, secondary ion | 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. (12 Dec 1998) |
| ionization | <chemistry, radiobiology> Any process by which a neutral atom gains or loses electrons, thus acquiring a net charge, as the dissociation of a substance in solution into ions or ion production by the passage of radioactive particles. High temperatures, electrical discharges or nuclear radiations can cause ionisation. (16 Dec 1997) |
| ionization chamber | A chamber for detecting ionization of the enclosed gas; used for determining intensity of ionizing radiation. (05 Mar 2000) |
| flame ionization | Pyrolysis of organic compounds at the temperature of a hydrogen-air flame to produce ionic intermediates which can be collected and the resulting ion current measured by gas chromatography. (12 Dec 1998) |
| clinical spectrometry | Spectroscopic determination of the types and amounts of various substances in living tissue or fluid from a living body. Synonym: clinical spectrometry. Origin: bio-+ L. Spectrum, an image, + G. Metron, measure (05 Mar 2000) |
| spectrometry | The procedure of observing and measuring the wavelengths of light or other electromagnetic emissions. (05 Mar 2000) |
| spectrometry, fluorescence | Measurement of the intensity and quality of fluorescence. (12 Dec 1998) |
| spectrometry, gamma | Determination of the energy distribution of gamma rays emitted by nuclei. (12 Dec 1998) |
| spectrometry, X-ray emission | Identification and measurement of concentration of elements based on the fact that X-rays emitted by an excited element have a wavelength characteristic of that element and an intensity related to its concentration. It includes fluorescence, or secondary-emission, X-ray spectrometry, in which the specimen is irradiated by X-rays. Primary-emission x-ray spectrometry, in which the specimen is bombarded by electrons, is a specific type of X-ray emission spectrometry known as electron probe microanalysis. (12 Dec 1998) |
| acute chemical pneumonitis | <chest medicine> Inflammation of the lungs which occurs secondary to exposure to a chemical, organic dust, fungus or mould. Chronic exposure can lead to chronic lung changes evident on chest X-ray. Symptoms include cough, fever, shortness of breath and wheezing. See: bird-handler's disease. (27 Sep 1997) |
| mechanico-chemical | Pertaining to, connected with, or dependent upon, both mechanics and chemistry; said especially of those sciences which treat of such phenomena as seem to depend on the laws both of mechanics and chemistry, as electricity and magnetism. Source: Websters Dictionary (01 Mar 1998) |
| chemical | 1. <chemistry> Of or pertaining to, chemistry. 2. A substance composed of chemical elements or obtained by chemical processes. (21 May 1997) |
| chemical and pharmacologic phenomena | Chemical, pharmacologic, and metabolic action and interaction of drugs. (12 Dec 1998) |
