【摘要】 采用TC-878专用红外定碳仪,利用电阻炉加热方式、红外测量原理测定了金属锂中的碳含量。进行了试样燃烧功率、称量选择等条件实验研究,实现了金属锂中碳量的快速测定,提高了测量结果的准确性和精确度。在试样取样量为20 mg,碳含量为100~600μg/g时,相对标准偏差优于15%,碳酸锂标准加入到金属锂中碳的回收率为91%~109%。更多还原

【Abstract】 The determination of carbon content in lithium metal was studied with TC-878 resistanceburning infrared C measure.The sampling combustion power and sampling amount were studied.So the carbon content in the sample can be determined quickly with better accuracy and precision.For sampling amount about 20 mg and carbon content of 100-600 μg/g,the relative standard deviation of is less than 15%,and the recovery of standard addition carbon is in the range from 91%to 109%.更多还原
