the use of spectroscopes to analyze spectra

Measuring the natural radio-activity of rocks; This radio-activity is due to potassium, thorium and uranium, contained in the rocks; an airborne spectrometric survey measures the radio-activity due to potassium, thorium and uranium in the rocks and as a consequence gives some information about the composition of the rocks.

Method commonly used to determine the chemical composition of an alloy.

An X-ray method used by fuel suppliers to analyse the quantity and type of wear metal present in gearbox and engine oil samples.

The process of identifying an unknown nucleus, atom, or substance by measuring the energy absorbed during excitation or emitted during de-excitation.

Measurement across a range of energies, where amplitude and energy are defined for each measurement. In gamma-ray spectrometry, the number of gamma rays are measured for each energy window, to define the spectrum.

Breaking up white light into its constituent wavelengths and measuring them on a calibrated scale.

an instrument used for measuring wavelengths of light

Art or process of using a spectrometer, of any type; -- when used alone, it usually refers to the use of a spectrometer using light in the visible, infrared, or ultraviolet region.
