Microscopic or photomicrographic technique for the visual counting of the numbers of particles in a known quantity of a solid-liquid suspension.
Industry:Chemistry
Polarography technique in which the rate of change of current with respect to applied potential is measured as a function of the applied potential (di/dE versus E, where i is current and E is applied potential).
Industry:Chemistry
A capillary column characterized by a layer of stationary liquid coated directly on the inner wall of a coiled capillary tube.
Industry:Chemistry
A method of trace analysis in which a beam of ions is directed at a thin foil on which the sample to be analyzed has been deposited, and the energy spectrum of the resulting x-rays is measured.
Industry:Chemistry
The use of a special resistance-capacitance network to record first and second derivatives of a thermometric titration curve (temperature versus weight change upon heating) to produce a sharp end-point peak.
Industry:Chemistry
1. In the purification of a laboratory sample, the cleaning of residual liquid impurities from precipitates by adding washing solution to the precipitates, mixing, then decanting, and repeating the operation as often as needed. 2. The removal of soluble components from a mixture of solids by using the effect of differential solubility.
Industry:Chemistry
Factor in light-scattering equations used to compensate for the loss in scattered light intensity caused by destructive interference during the analysis of macromolecular compounds.
Industry:Chemistry
A type of paper chromatography in which the sample-carrying solvent mixture is fed to the top of the developing chamber, being separated as it works downward.
Industry:Chemistry
A glass tube filled with a solid absorbent (calcium chloride or silica gel) to remove water from gaseous streams during or after chemical analyses.
Industry:Chemistry
Chromatographic procedure in which the stationary phase is a high-boiling liquid spread as a thin film on an inert support, and the mobile phase is a vaporous mixture of the components to be separated in an inert carrier gas.
