High pure F plastic sub-boiling distiller

Gao Chunfu plastic Asia seethes with excitement the distiller: 　　 In order to satisfy ICP, the ICP-MS extremely low examination to limit the demand to provide the laboratory level hyperpure acid distilling apparatus, this equipment uses the pressure regulator heating, causes the acid maintains Asia seethes with excitement the condition, again its sour steam cooling principle preparation hyperpure acid. 　　 This equipment uses the vessel uses F4 (teflon) and F46 (gathers the entire fluorine second grade propylene) anti-corrosive Gao Chunfu the plastic, therefore may process laboratory and so on nitric acid, hydrochloric acid, hydrofluoric acid commonly used acids, but not alteration, but this characteristic does not seethe with excitement for quartz Asia the distiller to have. 　　 The experiment proved that the majority of metal impurities content approximately the 10PPB acid depuration, after undergoing a distillation, the metal impurities content may reduce to 1PPB about, even is lower. If the para acid request is higher, may i
