Analytical chemistry
Thermal analysis
Chemistry; Analytical 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 ...
Matrix effects
Chemistry; Analytical 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 ...
Column development chromatography
Chemistry; Analytical 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 ...
Thermobalance
Chemistry; Analytical chemistry
An analytical balance modified for thermogravimetric analysis, involving the measurement of weight changes associated with the transformations of matter when heated.
Metal ion indicator
Chemistry; Analytical chemistry
A substance, usually a dyestuff, that changes colour after forming a metal ion complex with a colour different from that of the uncomplexed indicator. Also known as complexation indicator.
Combustion furnace
Chemistry; Analytical chemistry
A heating device used in the analysis of organic compounds for elements.
Thermogravimetric analysis
Chemistry; Analytical chemistry
Chemical analysis by the measurement of weight changes of a system or compound as a function of increasing temperature.
