摘要
应用甜菜品质分析仪测定了甜菜块根中钠的含量,添加回收率实验测得回收率在97.67%~98.67%之间,表明该方法具有较高的准确性。精密度试验结果表明:极差值在0.04%~0.06%之间,小于一般化学分析中含量范围0.1%~10%,标准偏差在0.015%~0.041%范围内,表明本方法的精密度较好,满足一般分析方法的要求。甜菜品质分析仪测量准确、误差小,速度快且精度高。
Sodium contents of sugarbeet root were determined by using Beet Quality Automation Analyzer.The results showed that the recovery rate was within 97.67%-98.67%,the range value of Na content was 0.04%-0.06%(less than generalization content of chemistry analysis 0.1%-10%) and the standard error was about 0.015%-0.041%.The results indicated that accuracy of the method of Beet Quality Automation Analyzer was comparatively high.The method was high accurate,fast and small error.
