Can meet the low detection limit requirements of ICP-OES and ICP-MS and provide laboratory-grade ultrapure acid for demanding analysis applications. The main body of the equipment is made of high-purity PTFE and PFA, and the container in contact with the acid reagent is made of imported PFA material. , lower background, no corrosion, no pollution, can handle HNO3, HCL, HF and other commonly used acids in laboratories. Experiments have shown that after a single distillation of an acid with a metal impurity content of about 10PPB, the metal impurity content can be reduced to about 0.01PPB. If the acid requirements are higher, the purification times can be increased. It is often used to extract high-purity acid in Ultra clean laboratories, trace analysis laboratories, geochemistry, marine systems, geology and minerals, geological brigade, polysilicon, materials and other industries. #Geochemistry #ICPMS #acidpreparation #acidpurification #traceanalysis
