Characterized as a spectrum from short wavelengths to long wavelengths
The distance traveled by one complete wave cycle measured in nanometers.
The measurement of light scattered by a particulate solution.
Measures the light blocked as a decrease in the light transmitted through the solution.
A process where atoms absorb energy at a particular wavelength, and the electrons release energy as they return to ground state by emitting light energy of a longer wavelength and lower energy than the exciting wavelength.
The emission of light produced by certain substances after they absorb energy.
The process where the chemical energy of a reaction produces excited atoms, and upon electron return to ground state, photons of light are emitted.
The process where an enzyme-catalyzed chemical reaction produces light emission.
A generic term for the type instrument that is used to measure chemiluminescence and bioluminescence
A technique where solutes in a sample are separated based on physical differences that allow their differential distribution between a mobile and stationary phase.
An instrument that uses the principle of charged particles moving through a magnetic or electric field, with ions being separated from other charged particles according to their mass to charge ratio.
Technique used to determine the concentration of a substance in solution employing an electrochemical cell that consists of two half-cells, where the potential difference between an indicator electrode and a reference electrode is measured.
