During absorption spectroscopy, the amount of radiant energy transmitted by the solution under analysis.
Industry:Chemistry
A method of detecting trace inpurities in a gas, in which the absorption of a sample of the gas at various light frequencies is measured by directing a periodically interrupted laser beam through the sample in a spectrophone and measuring the sound generated by the optoacoustic effect at the frequency of interruption of the beam.
Industry:Chemistry
The number of milligrams of copper obtained by the reduction of Benedict’s or Fehling’s solution by 1 gram of carbohydrate.
Industry:Chemistry
A scattered-light procedure for the determination of the weight concentration of particles in cloudy, dull, or muddy solutions; uses a device that measures the loss in intensity of a light beam as it passes through the solution. Also known as turbidimetry.
Industry:Chemistry
Quantitative determination of elements, functional groups, or molecules in organic materials.
Industry:Chemistry
A technique in which the amount of a substance is determined quantitatively by measuring the total amount of electricity required to deplete a solution of the substance.
Industry:Chemistry
Titration in which the end point is indicated by the developing turbidity of the titrated solution.
Industry:Chemistry
A device for measuring molecular weights by measuring the osmotic pressure exerted by solvent molecules diffusing through a semipermeable membrane.
Industry:Chemistry
The slow electrolytic generation of a soluble species which is capable of reacting quantitatively with the substance sought; some independent property must be observed to establish the equivalence point in the reaction.
Industry:Chemistry
1. Measure of the clarity of an otherwise clear liquid by using colorimetric scales. 2. Cloudy or hazy appearance in a naturally clear liquid caused by a suspension of colloidal liquid droplets or fine solids.
