DFY-12型高速定碳定硫自动分析仪(以下简称仪器),具有结构简单,操作简便,测定浓度范围较宽等优点。但在使用中对仪器的结构及合理选择实验条件尚存一些问题,因而影响仪器的应用推广。资料对应用作了有益的工作,本文作几点补充,以利这一高速分析更好推广应用。一仪器的结构原理剖析及其改进仪器的电气原理结构可分为四部分,如图1所示。 DFY-12 high-speed fixed-carbon sulfur analyzer (hereinafter referred to as instrument), has the advantages of simple structure, easy operation, determination of a wide range of concentrations. However, in the use of the instrument structure and reasonable choice of experimental conditions, there are some problems, thus affecting the application of the instrument to promote. Data on the application made a useful work, this article make a few supplements, to facilitate the high-speed analysis of better promotion and application. Analysis of the principle of an instrument structure and improve the electrical structure of the instrument structure can be divided into four parts, as shown in Figure 1.
