The plasma ashing instrument can complete the ashing of samples in a short time.

　Plasma ashing instrument, also known as plasma ashing equipment or plasma ashing furnace, is a device that uses plasma technology to oxidize and decompose organic matter in the sample at high temperature, thereby converting it into inorganic ash. Its core principle is to generate high-energy plasma, which can heat the sample to an ultra-high temperature in a short time and achieve rapid ashing of the sample.

Plasma generation: By injecting inert gas (such as argon) or reactive gas (such as oxygen) into the device and applying high-frequency electric field or microwave energy, the gas molecules are ionized to form plasma.

High-temperature oxidation: The high-energy electrons and ions in the plasma collide with the molecules on the surface of the sample, transferring energy to the sample, causing it to heat up rapidly and undergo oxidation reaction.

Ash formation: As the temperature rises, the organic matter in the sample is oxidized and decomposed into gases such as carbon dioxide and water vapor, while the inorganic matter is retained to form ash.

Application areas of plasma ashing instrument:

Material science: Used to analyze the composition and properties of materials, especially when studying high-temperature materials, ceramic materials and composite materials.

Environmental monitoring: used to process and analyze particulate matter in the air, pollutants in soil and sediments, and organic matter and heavy metals in water bodies.

Biomedicine: In biomedical research, it is used to analyze the elemental composition of biological tissues, cells and biomacromolecules.

Archaeology: In archaeological sites, it is used to analyze the chemical composition of ancient artifacts and remains to understand the lifestyle and environmental changes of ancient humans.

Advantages and characteristics

High efficiency and fast: Compared with traditional ashing methods, it can complete the ashing of samples in a short time, greatly improving work efficiency.

High temperature treatment: The high temperature of plasma can destroy organic matter in the sample and ensure the accuracy of ash content.

Pollution-free: By controlling the type and flow of gas, a pollution-free ashing process can be achieved.

Automated operation: It is usually equipped with an automated control system, which can realize automatic sampling, ashing, collection and data processing of samples.

With the continuous advancement of science and technology, the performance of plasma ashing instruments has been improved. In the future, it will be more intelligent and automated, with higher processing efficiency and a wider range of applications. At the same time, as people's awareness of environmental protection increases, pollution-free and low-energy plasma ashing technology will become a key research direction.
