Color-change indicator for acid-base titration end points in which a mixture of two indicator substances is used to give sharper end-point color changes.
Industry:Chemistry
The determination of the ligand/metal ratio in a coordination complex.
Industry:Chemistry
A method of analyzing the composition of a solution by adding known amounts of a standardized solution until a given reaction (color change, precipitation, or conductivity change) is produced.
Industry:Chemistry
1. In liquid chromatography, the phase that is moving in the bed, including the fraction of the sample held by this phase. 2. The carrier gas in a gas chromatography procedure.
Industry:Chemistry
A technique of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Also known as chelatometry. Also spelled compleximetric titration.
Industry:Chemistry
That range of values within which it has been calculated that a specified percentage of individual values of measurements will lie with a stated confidence level.
Industry:Chemistry
The difference between the molecular rotation at the extreme (peak or trough) value caused by the longer light wavelength and the molecular rotation at the extreme value caused by the shorter wavelength.
Industry:Chemistry
A sample comprising two or more increments selected to represent the material being analyzed.
Industry:Chemistry
Analysis of a very small quantity of material of a sample by such techniques as polarography or spectroscopy.
Industry:Chemistry
A U-tube variation of electrophoresis analysis that uses buffered solution so that all ions of a given species move at the same rate to maintain a sharp, moving front (boundary).
