我厂自1977年起,使用国产X射线荧光钙铁分析仪进行常规生产控制,迄今已有8年历史。使用效果令人满意。 仪器由探头和电子仪器二部分组成,探头内装有238Pu同位素源和正比计数管,该仪器结构牢固、性能稳定,可以昼夜连续使用。测量精确度为±0.14％CaO,±0.02％Fe2O3。原来用化学法分析CaCO3及Fe2O3需用精密天平、容器、试剂和电炉等,手续繁、速度慢,而且要求分析员技术高。X荧光分析法,只需取用一匙试样
I plant since 1977, the use of domestic X-ray fluorescence calcium and iron analyzer for routine production control, has been 8 years of history. Satisfactory results. The instrument consists of two parts: the probe and the electronic instrument. The probe is equipped with a 238Pu isotope source and a proportional counter tube. The instrument has the advantages of stable structure, stable performance and continuous use day and night. Measurement accuracy of ± 0.14% CaO, ± 0.02% Fe2O3. The original chemical analysis of CaCO3 and Fe2O3 need to use precision balances, containers, reagents and electric furnace, the procedure is complicated, slow, and require analysts with high technology. X fluorescence analysis, just take a spoonful of sample
