Sample Degasser Introduction
Flexible heating of samples between 25°C (77°F) and 400°C (752°F) depending on the different sample processing requirements; Sample degasser can remove moisture from the sample for drying function.
During sample heating, the treatment system can be optionally evacuated to effectively remove impurities adsorbed on the surface of the sample particles and achieve a cleaner treatment of the material.
For samples that should not be in contact with air, a protective gas can be injected during the processing as needed to achieve complete isolation of the sample from the air.
After the sample treatment, the protective gas is passed into the cooling process to realize the isolation and protection of the treated sample.
For samples with more moisture and impurities on the particle surface, the protective gas can be injected by the action of airflow to achieve the function of purging the sample surface, which is conducive to the faster and more thorough removal of impurities and moisture.
