摘要
研究了梅特勒 -托利多 82 2 e型差式扫描量热仪用于纯度测定的影响因素 .分别对扫描速率、样品重量、热阻 R0 、坩锅种类、装样与扫描技术等 5个影响因素进行了讨论 .结果表明 ,扫描速率、热阻 R0 、装样与扫描技术 3个因素对纯度测定结果影响较大 。
This paper studied the effects which were made on the determination of material purity by M-T 822 e differential scanning calorimeter(DSC). And five factors such as scanning rate, sample weight, thermo-resistance, pans and scanning technique, were discussed respectively. Result showed that scanning rate, thermo-resistance and scanning technique had some influences on the determination of purities, meanwhile sample weight and pans had little.
