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.
Device used for the analysis of the elements in a compound by fusing them with another compound; for example, analysis of nitrogen in organic compounds by fusing the compound with sodium and analyzing for sodium cyanide.
Industry:Chemistry
In chromatography, a measurement used in ion-exchange systems to express the adsorption ability of the ion-exchange materials.
Industry:Chemistry
The formation of a faithful mold or replica of a solid that is thin enough for penetration by an electron microscope beam; can use plastic (such as collodion) or vacuum deposition (such as of carbon or metals) to make the mold.
Industry:Chemistry
Analysis of the constituents or properties of a gas (either pure or mixed); composition can be measured by chemical adsorption, combustion, electrochemical cells, indicator papers, chromatography, mass spectroscopy, and so on; properties analyzed for include heating value, molecular weight, density, and viscosity.
Industry:Chemistry
One of the long, narrow (100 meters by 0.2–0.5 millimeter or 330 feet by 0.008–0.02 inch) columns used for capillary gas chromatography. Also known as open tubular column.
Industry:Chemistry
In gas chromatography, the relationship of retention volume with arbitrarily assigned numbers to the compound being analyzed; used to indicate the volume retention behavior during analysis.
Industry:Chemistry
The instrument used in gas chromatography to detect volatile compounds present; also used to determine certain physical properties such as distribution or partition coefficients and adsorption isotherms, and as a preparative technique for isolating pure components or certain fractions from complex mixtures.
Industry:Chemistry
A separation technique in which analytes are transported through a small-diameter packed column by electroosmosis (electrically induced flow of the mobile phase) by applying a high potential (5–30 kilovolts) across the column.
Industry:Chemistry
In gas chromatography, the time at which the center, or maximum, of a symmetrical peak occurs on a gas chromatogram.
Industry:Chemistry
A separation technique involving passage of a gaseous moving phase through a column containing a fixed adsorbent phase; it is used principally as a quantitative analytical technique for volatile compounds.
