Industry:Chemistry
A device used in the quantitative analysis of the carbon and hydrogen content of organic compounds.
Industry:Chemistry
A nonchelating dye used to improve the colorimetric end point of a complexometric titration; a dye addition forms a complementary pair of colors with the metalized and unmetalized forms of the end-point indicator.
Industry:Chemistry
A device to measure and record the weight of sediment (solid particles settled out of a liquid) versus time; used to determine particle sizes of fine solids.
Industry:Chemistry
The equilibrium between the forward movement of a sample’s liquid-sediment boundary and reverse diffusion during centrifugation; used in molecular-weight determinations.
Industry:Chemistry
The rate of movement of the liquid-sediment boundary in the sample holder during centrifugation; used in molecular-weight determinations.
Industry:Chemistry
Liquid solution of known chemical composition and concentration, hence of known and standardized color, used for optical analysis of samples of unknown strength.
Industry:Chemistry
Reagent used to analyze for phosphorus; consists of the filtered liquor from an aqueous mixture of ammonium chloride, magnesium sulfate, and ammonia.
Industry:Chemistry
The quantitative analysis of a substance by comparing the intensity of the color produced in a sample by a reagent with a standard color produced similarly in a solution of known strength.
