分析明胶中的铬（Cr）元素（火焰法）

In the Japanese Pharmacopoeia Sixteenth Edition promulgated by the Ministerial Notification No. 65 of the Ministry of Health, Labour and Welfare in 2011, the General Tests, Processes and Apparatus and Official Monographs are to be partly revised, and the edition will be issued and become effective in May, 2013. In the draft revision, the section of chromium is added for the Purity of gelatin and the flame atomic absorption spectrophotometry is to be employed as the analysis method. ZA3000 series instruments employ the polarized Zeeman method for BKG corrections even for the flame method. The accurate BKG corrections and a stable baseline allow the sufficient analysis of chromium at 1/2 the level of the specification (draft).
