鉴于全国各666主要生产厂分析方法不一致,具体地说极谱波高测量的不一致,造成产品分析结果相差很大。为此化工部在沈阳召开哇66极谱分析短训班,以统一测试方法,施行两线定点定位法作图,贯彻GB332-77国家标准。据统计,全国有25家666工业原粉主要生产厂,所用本厂883型笔录式极谱仪有20家,占全国的80%。由于仪器的使用年限、仪器的性能与精度、仪器的运转与维修情况不同,
In view of inconsistencies in the analytical methods of the major 666 major manufacturing plants in the country, specifically the inconsistency of the polarographic wave height measurements, the result of the product analysis varies greatly. To this end the Ministry of Chemical Industry held in Shenyang wow 66 polarographic short training classes, a unified test method, the implementation of two-line fixed-point positioning mapping, the implementation of GB332-77 national standards. According to statistics, there are 25 main factories of 666 industrial raw powders nationwide, and there are 20 883 type recorded polarographs, accounting for 80% of the country’s total. Due to the service life of the instrument, the performance and accuracy of the instrument, the operation and maintenance of the instrument are different,
