The study and measurement of spectra and their components.

Spectrometric analysis of the distinct and characteristic spectra of atoms of elements. The atoms are energized to emit radiant energy, which, when dispersed by a prism or diffraction grating,...

The procedure applied to flame-excited line emissions to determine spectra and wavelengths.

Mass spectrometry (MS) is an analytical technique used to determine the molecular composition and structure of compounds based on their mass-to-charge ratio (m/z). It involves ionizing chemical...

The recording and mathematical analysis of all spectral intervals of the spectrometer simultaneously.

The method of determining the energy distribution of high-speed charged particles by the luminous effect formed when the particles strike a material.

Time-resolved ultraviolet photodissociation mass spectrometry (TR-UV-PDMS) is a specialized analytical technique used in mass spectrometry to study the dynamics of chemical reactions, molecular...

Chemical sensing refers to the detection and measurement of specific chemical compounds or substances in various environments or samples. It involves the use of sensors or analytical techniques to...
