Placing a few drops of potassium iodide solution on a sample to detect the presence of starch; test is positive if sample turns blue.
Industry:Chemistry
Preferential adsorption of chemical compounds (gases or liquids) in an ascending molecular-weight sequence onto a solid adsorbent material, such as activated carbon, alumina, or silica gel; used for analysis and separation of chemical mixtures.
Industry:Chemistry
Situation when the desired directions for analysis of energy from (reflected from) an object under spectrophotometric colorimetric analysis is diffused in all directions (not directed as a single beam).
Industry:Chemistry
An application of iodine chemistry to oxidation-reduction titrations for the quantitative analysis in certain chemical compounds, in which iodine is used as a reductant and the iodine freed in the associated reaction is titrated, usually in neutral or slightly acid mediums with a standard solution of a reductant such as sodium thiosulfate or sodium arsenite; examples of chemicals analyzed are copper(III), gold(VI), arsenic(V), antimony(V), chlorine, and bromine.
Industry:Chemistry
Any of the different configurations in which the stationary phase is contained.
Industry:Chemistry
A cell containing the sample in the optoacoustic detection method; equipped with windows through which the laser beam enters the cell and a microphone for detecting sound.
Industry:Chemistry
Device for detection of presence or concentration of liquid solution ions, such as with a pH meter or by conductimetric techniques.
Industry:Chemistry
A method of separating and analyzing mixtures of chemical substances by chromatographic adsorption.
Industry:Chemistry
A chromatographic procedure in which the stationary phase consists of ion-exchange resins which may be acidic or basic.
Industry:Chemistry
Electroanalysis by measuring at a working electrode the rate of change of current versus time during a titration; the potential is controlled.
