我院自一九七四年开始微库仑滴定系统定硫分析仪的研究探索工作,先后完成“微量总硫分析装置”、“轻油中微量硫分析仪”样机及“WKL—Ⅰ型微库仑定硫仪”的研制。WKL～Ⅰ型微库仑定硫仪已于一九七九年通过化工部技术鉴定,监由专业厂生产,已广泛用于化肥、石油化工等生产厂及研科单位。为了使仪器能适合多种硫分析的要求,提高仪器性能,我们在总结WKL—Ⅰ型仪器研制基础上,又对滴定系统、微库仑计与分析操作条件进行了研究,完成了WKL一Ⅱ型微库仑定硫仪的研制。
Since 1984, our institute has started the exploration and research on the fixed-sulfur analyzer for the microcoulometric titration system. We have completed the “Total Sulfur Analysis Device”, the “Sulfur Analyzer for Light Oil” and the “WKL-Ⅰ Microcoulomb Sulfur Meter ”development. WKL ~ Ⅰ microcoulometry sulfur analyzer passed the technical appraisal of Ministry of Chemical Industry in 1979, supervised by professional factory production, which has been widely used in fertilizer, petrochemical and other production plants and research units. In order to make the instrument suitable for a variety of sulfur analysis requirements and improve the performance of the instrument, we summarize the development of WKL-Ⅰ instrument based on the study of the titration system, the microcoulometry and analysis of operating conditions, completed a WKL Ⅱ type Development of microcoulometry sulfur analyzer.
