Analytical chemistry
spectral directional reflectance factor
Chemistry; Analytical chemistry
In spectrophotometric colorimetry, the ratio of the energy diffused in any desired direction by the object under analysis to that energy diffused in the same direction by an ideal perfect (energy) ...
iodine number
Chemistry; Analytical chemistry
A measure of the iodine absorbed in a given time by a chemically unsaturated material, such as a vegetable oil or a rubber; used to measure the unsaturation of a compound or mixture. Also known as ...
spectral radiance factor
Chemistry; Analytical chemistry
A situation when the desired directions for analysis of energy diffused from (reflected from) an object under spectrophotometric colorimetric analysis are all substantially the same (a solid angle of ...
iodine test
Chemistry; Analytical chemistry
Placing a few drops of potassium iodide solution on a sample to detect the presence of starch; test is positive if sample turns blue.
chromatographic adsorption
Chemistry; Analytical 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 ...
spectral reflectance
Chemistry; Analytical 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 ...
