Analytical chemistry

Paper electrophoresis

Chemistry; Analytical chemistry

A variation of paper chromatography in which an electric current is applied to the ends of the electrolyte-impregnated absorbent paper, thus moving chargeable molecules of the unknown sample toward ...

Density gradient centrifugation

Chemistry; Analytical chemistry

Separation of particles according to density by employing a gradient of varying densities; at equilibrium each particle settles in the gradient at a point equal to its density.

Volumetric analysis

Chemistry; Analytical chemistry

Quantitative analysis of solutions of known volume but unknown strength by adding reagents of known concentration until a reaction end point (color change or precipitation) is reached; the most ...

Paper-tape chemical analyzer

Chemistry; Analytical chemistry

Chemically treated paper tape that is continuously unreeled, exposed to the sample, and viewed by a phototube to measure the colour change that is empirically related to changes in the sample’s ...

Derichment

Chemistry; Analytical chemistry

In gravimetric analysis by coprecipitation of salts, a system with _ less than unity, when _ is the logarithmic distribution coefficient expressed by the ratio of the logarithms of the ratios of the ...

Volumetric flask

Chemistry; Analytical chemistry

A laboratory flask primarily intended for the preparation of definite, fixed volumes of solutions, and therefore calibrated for a single volume only.

Paramagnetic analytical method

Chemistry; Analytical chemistry

A method for analysing fluid mixtures by measurement of the paramagnetic (versus diamagnetic) susceptibilities of materials when exposed to a magnetic field.
