Industry:Chemistry
A technique of bonded-phase chromatography in which the stationary phase is polar and the mobile phase is nonpolar.
Industry:Chemistry
A material of known composition that is analyzed along with test samples in order to evaluate the accuracy of an analytical procedure. Also known as check sample.
Industry:Chemistry
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.
