A device for measuring the relative amounts of radiant energy or radiant flux as a function of wavelength. An instrument for measuring the amount of light absorbed by a sample. An instrument used to measure the intensity of wavelengths in a spectrum of light compared with the intensity of light from a standard source. Determination of the concentration of a material in a sample by measurement of the amount of light the sample absorbs. Spectroradiometers are measurement devices used to determine the amount of light emitted by a device such as a lamp, computer screen or television screen.
Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution.
BritishHealthMedicineA sphincter is an anatomical structure, a circular muscle that normally maintains constriction of a natural body passage or orifice and which relaxes as required by normal physiological functioning. Sphincters are found in many animals; there are over 50 types in the human body, some microscopically small, in particular the millions of precapillary sphincters. Sphincters relax at death, possibly releasing fluids.
