Abstract

Direct-reading spectrometer is an effective equipment for metal analysis. How to determine the technical specification of DF-100 direct-reading spectrometer for analysis of stainless steel is described. Through inspection service comparing with the similar equipments precision of overseas companies

such as Spectro and ARL ect

the results show that the performance curve of DF-100 direct-reading spectrometer satisfies long-term use and doesn’t need to be re-draw. The determination of sample reproductivity is high and the instrument is stable during long-term stability service. It can not only meet the requirment of stainless steel analysis

but also save the massive demarcation time and chemical reagents. The analytical precision of element determination of stainless steel is level with overseas similar equipments.
