摘要
应用2400/2460自动进样定氮仪对复混肥料中总氮含量进行测定,本文考察了方法的准确性和重现性。实验数据表明,2400/2460自动进样定氮仪测定复混肥料中总氮含量具有良好的准确性和重现性,该方法与GB/T 8572-2010蒸馏后滴定法进行了样品比对试验,经过数据统计分析,显示了测试结果的一致性,自动进样定氮仪具有更快速、简便的优点,特别适用于大批量样品的检测。
The total nitrogen content of compound fertilizer was determined by using 2400/2460 fully-automatic nitrogen analyzer, in which the accuracy and reproducibility of the method was evaluated and the results showed that the method has good accuracy and reproducibility for determination of total nitrogen content in compound fertilizer, this method and GB/T 8572-8572 Titration method after distillation for the sample comparison test, through statistical analysis, shows the consistency of the test results, the method also had the advantages of more rapid and convenient, especially suitable for large quantities of the detection of the sample.
