In the conventional laboratory analysis, each kind of acid and the reagent are widely applied in the daily sample preparation and the analysis. However, those who make the numerous consumers to feel has a headache is each kind of acid and the reagent purity. Because many laboratories the acid purity is frequently bad, creates the analysis result the deviation and the mistake. At present, many laboratories use in the trace analysis in the purchase very expensive hyperpure acid (in the US, five liter hyperpure nitric acid's prices approximately are $ 1,500.00). As a result of market hyperpure acid because the price is often expensive, very difficult to satisfy in the daily analysis the para acid keen demands. Therefore, deputes the superior acidify the quality, is the most economical feasible way. the Jintan positive radical instrument Limited company produces the syz-s acid distillation purification system, aims at a section of high grade purification system which the user community the analysis demand designs. Is different what with other products, this system uses the high quality natural quartz depuration production completely, and the purity may achieve 4 nine quartz glass. With the acid contact's quartz part part, guarantees the material quality absolutely the purity. Does not have the pollution and the corrosion certainly. this system uses the infrared radiation heating, causes the acid maintains Asia seethes with excitement the condition, again its sour steam cooling principle preparation hyperpure acid. The entire distillation process is at the closed state, the experiment proved that in the acid depuration process, after undergoing a distillation, the impurity single item content may reduce to 5PPB about; Will depute the impurity single item content many times about 5ppt, will be lower; If the para acid request is higher, may increase the depuration number of times. Definitely may satisfy ICP, the ICP-MS extremely low examination demand. Is the preparation hyperpure acid and the depuration reagent first choice of instrument.
