In analytical chemistry, ashing or ash content determination is the process of mineralization by complete combustion for preconcentration of trace substances prior to a chemical analysis, [1] such as chromatography, or optical analysis, such as spectroscopy.

Ashing in analytical chemistry is defined as the heating of a substance to leave only noncombustible ash, which is analyzed for it's elemental composition. The sample preparation techniques incorporating some form of 'ashing' are as follows:

'Ashing' is a procedure used in chemistry to remove organic carbon and other volatile species from samples, resulting in thinning the sample and enhancing the concentrations of remaining elements for easier analysis.

In semiconductor manufacturing plasma ashing is the process of removing the photoresist (light sensitive coating) from an etched wafer. Using a plasma source, a monatomic (single atom) substance known as a reactive species is generated.

Ashing is the process of removing organic material from a sample before analysis and is widely used in the food and petroleum industries. The processes of ashing can generally be split into two categories: wet ashing and dry ashing.

2020年2月13日 · Ashing, the process of removing organic material from a sample prior to analysis, is widely used in the food and petroleum industries. Ashing methodologies can be broadly split into two categories: wet ashing and dry ashing.

Ashing refers to the process of removing organic material from a sample by heating it to high temperatures until only inorganic residues remain. This is typically done in a controlled environment, such as a furnace, to ensure complete combustion of the organic material.

2017年6月7日 · Ashing is an important first step in proximate or specific mineral analysis. Ash refers to the inorganic (mineral) residue remaining after the combustion or complete acid-facilitated oxidation of organic matter in food. This chapter covers the instrumentation,...
