Rapid Determination of Total Ash in Rubber Stoppers by Thermogravimetric Analysis

  • 摘要: 针对药用丁基胶塞的灰分指标,考察了热重分析法的反应温度和恒温时间对测试结果的影响,优化了热重分析法测定胶塞灰分的检测方法. 方法测得的胶塞灰分值相对标准偏差为0.01%,且测试耗时少于1 h. 在缩短检测时间的同时,检测结果的准确性和重现性均优于用方法YBB00262005和方法ASTM D6370-99检测所获得的结果.

     

    Abstract: A rapid method to determine the total ash content in rubber stoppers is established using thermogravimetric analysis. The effect of different testing conditions on the results is studied as well. The relative standard deviation of the total ash obtained is 0.01% and the experimental time is less than 1h. The repeatability and accuracy of this method have been demonstrated better than that of YBB00262005 and ASTM D6370-99 methods.
