概述
永停滴定法是容量分析中確定終點的一種方法。自動永停滴定儀是根據(jù)中國藥典77版所載的永停滴定法的要求而試制成功的一種新型儀器，并收載2000版藥典，用作于重氮化測定終點指示，它與外指示劑和觀察費體試液變化結果等比較，具有精度高、測定準確、使用方便、小巧輕便、性能穩(wěn)定等優(yōu)點。它是化學實驗室、藥品檢驗所、各大醫(yī)院、制藥廠、獸藥廠、飼料廠等進行醫(yī)藥化工等工業(yè)溶量分析的一的測定儀器。
GENERAL
Ascertaining end-point titrimetry is a method to ascertain the end-pointin volumetric analysis, the automatic ascertaining end-point titratoris a new instrument manufac-tured according to the requirement of Titrimetry recorded Chinese Codex（Edition:77）which can be used to measure dia-zonium end-point indication. It has the advantages suchas high precision , exact measurement, convenient usage, stable performance compared with the methodsof using external indicator and watching Fischer liquid ,It is an abso-luy necessaryinstrument to analyze solution for chemical labs, physic in-spection organizations, hospitals, phar-maceutical factory and so on
