An analytical technique for identification of chemical structures, determination of mixtures, and quantitative elemental analysis, based on application of the mass spectrometer.
Industry:Chemistry
In chromatography, a tube holding the stationary phase through which the mobile phase is passed.
Industry:Chemistry
Any chemical separation technique using chromatography in which a supercritical fluid is used as the mobile phase.
Industry:Chemistry
In analysis by mass spectroscopy, the measurement of the sample mass as a ratio to its ionic charge.
Industry:Chemistry
The loss of carrier liquid during gas chromatography due to evaporation into the gas under analysis.
Industry:Chemistry
A capillary column that utilizes a finegranular solid support to disperse the stationary liquid.
Industry:Chemistry
The analyte as considered in terms of its being an assemblage of constituents, each with its own properties.
Industry:Chemistry
Chromatographic technique of two general types: packed columns usually contain either a granular adsorbent or a granular support material coated with a thin layer of high-boiling solvent (partitioning liquid); open-tubular columns contain a thin film of partitioning liquid on the column walls and have an opening so that gas can pass through the center of the column.
Industry:Chemistry
Analytical techniques developed to continuously monitor physical or chemical changes of a sample which occur as the temperature of a sample is increased or decreased. Thermogravimetry, differential thermal analysis, and differential scanning calorimetry are the principal thermoanalytical methods.
Industry:Chemistry
1. The enhancement or suppression of minor element spectral lines from metallic oxides during emission spectroscopy by the matrix element (such as graphite) used to hold the sample. 2. The combined effect exerted by the various constituents of the matrix on the measurements of the analysis.
