Absorption Spectroscopy

Science / Chemistry / Absorption Spectroscopy: A technique for determining the concentration and structure of a substance by measuring the amound of electromagnetic radiation the sample absorbs at various wavelengths.

Reabsorption

Science / Biology / Reabsorption: The return to the blood of most of the water, sodium, amino acids, and sugar that were removed during filtration; occurs mainly in the proximal tubule of the nephron. MORE

Specific Absorption Rate (SAR)

Technology / Cell Phones / Specific Absorption Rate (SAR): A measure of the rate at which RF energy is absorbed by the body. MORE

Spectroscopy

Science / Chemistry / Spectroscopy: Spectroscopy is analysis of the interaction between electromagnetic radiation and matter. Different types of radiation interact in characteristic ways with different samples of matter; the interaction MORE

Absorption

Science / Biology / Absorption: The process by which the products of digestion are transferred into the bodys internal environment, enabling them to reach the cells. MORE

Infrared Spectroscopy

Science / Chemistry / Infrared Spectroscopy: A technique for determining the structure (and sometimes concentration) of molecules by observing how infrared radiation is absorbed by a sample. MORE

Absorption Spectrum

Science / Chemistry / Absorption Spectrum: A plot that shows how much radiation a substance absorbs at different wavelengths. Absorption spectra are unique for each element and compound and they are often used as chemical 'fingerprints' in ana MORE
