Glossary


EVISA is providing a list of terms used in the area of speciation and fractionation analysis. Since speciation analysis is a field of analytical chemistry that is specified by a pronounced interdisciplinary cooperation between different sciences such as biochemistry, medicine, biology, environmental sciences, nutritional sciences and material sciences its terminology is a complex mixture of terms used in all these.

You may search for a term or browse the glossary alphabetically.

(In case that you cannot find the term you may consult more special glossaries or handbooks about nomenclature. For more details please consult EVISA's List of Glossaries)

kinetic energy discrimination (KED)
A process that uses collisions with a neutral gas to reduce the axial velocity of larger, molecular ions more extensively than smaller, elemental ions so that the transmission efficiency of elemental ions through a collision/reaction cell is larger than the transmission efficiency of molecular ions.

kinetics
(in chemistry)
Branch of chemistry concerned with neasuring and studying rates of chemical reactions.
