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.
A circular disk of absorbent paper which has a strip (wick) cut from edge to center to dip into a solvent; the solvent climbs the wick, touches the sample, and resolves it into concentric rings (the chromatogram). Also known as circular chromatography; radial paper chromatography.
Industry:Chemistry
The ratio of the departure of the chromaticity of a specified color to that of the reference source, measured on a chromaticity diagram; used as a guide of the wavelength of spectrum color needed to be mixed with a reference color to give the specified color.
Industry:Chemistry
A systematic error occurring in a chemical measurement that is inherent in the method itself or caused by some artifact in the system, such as a temperature effect.
Industry:Chemistry
An assay procedure involving the measurement of the radiation intensity of a radioactive sample.
Industry:Chemistry
A performance characteristic of an analytical chemical method that influences its choice for a specific type of determination, such as selectivity, sensitivity, detection limit, precision, and bias.
Industry:Chemistry
A method for quantitatively determining the concentration of a substance by its effect on the growth of a suitable animal, plant, or microorganism under controlled conditions.
Industry:Chemistry
An analytic process for quantitative or qualitative determination of radioactive substances in a mixture by measuring the radioactivity of various zones in the chromatogram.
Industry:Chemistry
Liquid-analysis chromatographic technique in which the stationary phase (adsorbent) is a strip or layer, as in paper or thin-layer chromatography.
Industry:Chemistry
A bioassay based upon the ability of some compounds (for example, vitamin B<sub>12</sub>) to enhance the growth of some organisms or compounds and to repress the growth of others; used to assay certain antibiotics.
Industry:Chemistry
An analytical technique including procedures for separating and reproducibly measuring a radioactive tracer.
