| Abstract: | Gives a brief account on the determination of metal elements content in milk powder by a rapid dry-ashing, and makes a comparison test between the normal dry process, wet process and rapid dry-ashing. The retrieval and precise tests were carried out by three processes.According to statistic analysis these results show that the rapid dry-ashing is accurate and rcliatlc. The accuracy and precision of the rapid dry-ashing are the best over others. |
