Analytical chemistry
Radial chromatography
Chemistry; Analytical chemistry
A circular disc of absorbent paper which has a strip (wick) cut from edge to centre to dip into a solvent; the solvent climbs the wick, touches the sample, and resolves it into concentric rings (the ...
Excitation purity
Chemistry; Analytical chemistry
The ratio of the departure of the chromaticity of a specified colour to that of the reference source, measured on a chromaticity diagram; used as a guide of the wavelength of spectrum colour needed ...
Bias
Chemistry; Analytical chemistry
A systematic error occurring in a chemical measurement that is inherent in the method itself or caused by some artefact in the system, such as a temperature effect.
Radioassay
Chemistry; Analytical chemistry
An assay procedure involving the measurement of the radiation intensity of a radioactive sample.
Figure of merit
Chemistry; Analytical chemistry
A performance characteristic of an analytical chemical method that influences its choice for a specific type of determination, such as selectivity, sensitivity, detection limit, precision, and bias.
Bioassay
Chemistry; Analytical chemistry
A method for quantitatively determining the concentration of a substance by its effect on the growth of a suitable animal, plant, or microorganism under controlled conditions.
Radiochromatography
Chemistry; Analytical chemistry
An analytic process for quantitative or qualitative determination of radioactive substances in a mixture by measuring the radioactivity of various zones in the chromatogram.
