在石化行业中,为保证产品质量和装置的生产安全,必须对原料气体中的氧含量进行监控分析,其中所使用的主要分析手段之一就是微量氧分析仪。微量氧分析器的种类很多,按照工作原理主要可分为四种:即磁式,氧化锆式,燃料电池式及赫兹电池式。对于不同类型的仪器,在使用及维护方面都有所不同。下面就结合我厂使用的美国ADV公司生产的GPR-12MS型便携式微量氧分析仪,来介绍一下该种类型仪器的使用和维护的注意事项。
In the petrochemical industry, in order to ensure product quality and plant safety, the oxygen content in the feed gas must be monitored and analyzed. One of the main analytical methods used is the micro-oxygen analyzer. There are many types of trace oxygen analyzer, according to the working principle can be divided into four types: the magnetic type, zirconia type, fuel cell type and Hertz cell type. Different types of instruments, in the use and maintenance are different. The following combined with our plant used by the United States ADV GPR-12MS portable micro-oxygen analyzer, to introduce the type of instrument use and maintenance considerations.
