Analytical chemistry

sedimentation equilibrium

Chemistry; Analytical chemistry

The equilibrium between the forward movement of a sample’s liquid-sediment boundary and reverse diffusion during centrifugation; used in molecular-weight determinations.

A method of measuring the moisture content of a gas in which a known volume of gas is passed through a suitable desiccant, such as phosphorus pentoxide or silica gel, and the change in weight of the ...

carrier gas

Chemistry; Analytical chemistry

In gas chromatography, a gas used as an eluant for extracting the sample from the column as the gas passes through. Also known as eluant gas.

sedimentation velocity

Chemistry; Analytical chemistry

The rate of movement of the liquid-sediment boundary in the sample holder during centrifugation; used in molecular-weight determinations.

gravimetric analysis

Chemistry; Analytical chemistry

That branch of quantitative analytical chemistry in which a desired constituent is converted, usually by precipitation or combustion, to a pure compound or element, of definite known composition, and ...
