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 various components are preferentially held at different rates, effecting a separation.
Industry:Chemistry
An analytical balance modified for thermogravimetric analysis, involving the measurement of weight changes associated with the transformations of matter when heated.
Industry:Chemistry
A substance, usually a dyestuff, that changes color after forming a metal ion complex with a color different from that of the uncomplexed indicator. Also known as complexation indicator.
Industry:Chemistry
A heating device used in the analysis of organic compounds for elements.
Industry:Chemistry
Chemical analysis by the measurement of weight changes of a system or compound as a function of increasing temperature.
Industry:Chemistry
In mass spectroscopy, an ion formed by a secondary dissociation process in the analyzer tube (formed after the parent or initial ion has passed through the accelerating field).
Industry:Chemistry
A type of enthalpimetric analysis which uses kinetic titrimetry; involves rapid and continuous automatic delivery of a suitable titrant, under judiciously controlled experimental conditions with temperature measurement; the end points obtained are converted by mathematical procedures into valid stoichiometric equivalence points and used for determining reaction rate constants.
Industry:Chemistry
Identification and chemical analysis of material on a small scale so that specialized instruments such as the microscope are needed; the material analyzed may be on the scale of 1 microgram.
Industry:Chemistry
A glass, silica, or porcelain tube, resistant to high temperatures, that is a component of a combustion train.
