从直读光谱仪的光路结构入手,对JJG 768–2005《发射光谱仪》中直读光谱仪部分的波长示值误差、检出限以及重复性和稳定性等检定项目和方法进行了讨论。研究发现,规程存在波长示值误差部分表述不准确、检出限和重复性、稳定性技术指标不详尽等问题。针对上述问题,建议修改“波长示值误差”这一表述,并将其作为后续检定的非必检项;在检出限检定部分对标准物质铁的含量加以要求,并注明元素分析谱线的波长值;对重复性和稳定性选用的标准物质作出元素含量范围的规定,以防造成误判。
從直讀光譜儀的光路結構入手,對JJG 768–2005《髮射光譜儀》中直讀光譜儀部分的波長示值誤差、檢齣限以及重複性和穩定性等檢定項目和方法進行瞭討論。研究髮現,規程存在波長示值誤差部分錶述不準確、檢齣限和重複性、穩定性技術指標不詳儘等問題。針對上述問題,建議脩改“波長示值誤差”這一錶述,併將其作為後續檢定的非必檢項;在檢齣限檢定部分對標準物質鐵的含量加以要求,併註明元素分析譜線的波長值;對重複性和穩定性選用的標準物質作齣元素含量範圍的規定,以防造成誤判。

Several important performance indexes of emission spectrometer were discussed such as indication error of wavelength, detection limit, repeatability and stability via investigating the structure and principle of the monochromator and detector. The research revealed that the definitions of indication error of wavelength was inappropriate, while, some necessary restrictions were not mentioned in terms of detection limit, repeatability and stability. Meanwhile, some suggestions were proposed such as improving the description of wavelength indication error, restricting the purity of reference material as testing the detection limit,repeatability and stability.
