McGraw Hill Financial, Inc. is an American publicly traded corporation headquartered in Rockefeller Center in New York City. Its primary areas of business are financial, publishing, and business services.
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.
Industry:Chemistry
Columnar apparatus for separating or concentrating one or more components from a physical mixture by use of adsorbent packing; as the specimen percolates along the length of the adsorbent, its various components are preferentially held at different rates, effecting a separation.
Industry:Chemistry
An analytical balance modified for thermogravimetric analysis, involving the measurement of weight changes associated with the transformations of matter when heated.
Industry:Chemistry
A substance, usually a dyestuff, that changes color after forming a metal ion complex with a color different from that of the uncomplexed indicator. Also known as complexation indicator.
