摘要
介绍了使用微库仑仪测己二酸二甲酯中硫含量的方法。汽化端温度设置为600℃,燃烧端温度设置为800℃,偏压150 mV,增益200,采样电阻2 kΩ,10 ng/μL的硫标准溶液,进样体积8.0μL,5次测得平均转化率为102%,测得己二酸二甲酯样品中的硫含量平均值为8.70 ng/μL,结果的相对标准偏差为2.64%。
Microcoulometer was applied to the determination of sulfur content in dimethyl adipate sample. The temperature of vaporizer of 600℃, the temperature of eombustor of 800℃, offset voltage of 150 mY, yield value of 200 and sampling resistance of 2 kΩ were set to determine the sulfur content. With inlet amount of 8.0μL, after five determination of 10ng/μL standard solution, average conversion obtained was 102%, average sulfur content in dimethyl adipate sample obtained was 8.70 ng/μL and RSD of the results was 2.64 %.
