Oxygen bomb combustion sample processing device is a pretreatment device for the analysis of non-metallic elements in organic samples. The samples are burned in a airtight pure oxygen system. The components to be measured are released from the sample and absorbed by the absorbent liquid placed in the oxygen bottle. Then the absorbent liquid can be analyzed by IC. It is widely used in quantitative analysis of heavy metals and harmful halogen elements in electrical plastics products and circuit boards.
