测定低碳的方法有电导法、库仑法、红外分光法、色谱法等。其中,电导法仪器装置较简单,灵敏度高。故近年来对这一方法,特别是电导仪的设计,仍在不断作研究和改进。在钢铁分析中,电导定碳法已被有的国家列为标准分析方法。我国冶金部也拟将这一方法列入部颁标准方法(草案)。为了能满足测定低碳的需要,我们探讨了影响电导定碳仪精度的一些因素,设计了一种装置较简单、精密度和灵敏度均较高的DDJ-201型电导定碳仪,并对该仪器进行了必要的考核。仪器将由上海
Determination of low-carbon method conductivity method, coulometry, infrared spectroscopy, chromatography and so on. Among them, the conductivity method apparatus is simple, high sensitivity. Therefore, in recent years, this method, especially the design of the conductivity meter, is still under continuous research and improvement. In the steel analysis, electrically-conductive carbon method has been listed as a standard method in some countries. The Ministry of Metallurgy also plans to include this method in the ministerial standard method (draft). In order to meet the needs of the determination of low carbon, we discussed some of the factors that affect the accuracy of the conductivity carbonator, designed a simple device, the precision and sensitivity are high DDJ-201-type conductivity-carbon instrument, and the The instrument conducted the necessary assessment. The instrument will be from Shanghai
