Generic designation for a group of modern thermochemical methodologies such as thermometric enthalpy titrations which rely on monitoring the temperature changes produced in adiabatic calorimeters by heats of reaction occurring in solution; in contradistinction, classical methods of thermoanalysis such as thermogravimetry focus primarily on changes occurring in solid samples in response to externally imposed programmed alterations in temperature.
Industry:Chemistry
1. Titration with quantitative reaction and measured flow of reactant. 2. Electrically generated reactant with potentiometric, ampherometric, or colorimetric end-point or null-point determination.
Industry:Chemistry
A type of mass spectroscope in which ions pass along a line of symmetry between four parallel cylindrical rods; an alternating potential superimposed on a steady potential between pairs of rods filters out all ions except those of a predetermined mass. Also known as Massenfilter.
Industry:Chemistry
Interference microscopy technique utilizing the Sabattier effect in photographic emulsions; the equidensities (lines of equal density in a photographic emulsion) are produced by exactly superimposing a positive and a negative of the same interferogram, and making a copy; used to measure photographic film emulsion density.
Industry:Chemistry
The position and spread of a solute within a series of tubes in a liquid-liquid extraction procedure. Also known as zone.
Industry:Chemistry
The analysis of a gas, liquid, or solid sample or mixture to identify the elements, radicals, or compounds composing the sample.
Industry:Chemistry
A technique used to determine the degree of ion bonding by protein; the protein solution, placed in a bag impermeable to protein but permeable to small ions, is immersed in a solution containing the diffusible ion whose binding is being studied; after equilibration of the ion across the membrane, the concentration of ion in the protein-free solution is determined; the concentration of ion in the protein solution is determined by subtraction; if binding has occurred, the concentration of ion in the protein solution must be greater.
Industry:Chemistry
A method for measurement of absorption peaks for quantitative analysis of chemical compounds in which a base line is drawn tangent to the spectrum background; the distance from the base line to the absorption peak is the absorbence due to the sample under study.
Industry:Chemistry
The analysis of a gas, liquid, or solid sample or mixture to determine the precise percentage composition of the sample in terms of elements, radicals, or compounds.
Industry:Chemistry
The ordinary and commonplace elements of life, as distinguished from the sacred.
