采用安捷伦双等离子体硫化学发光检测器和7890A 气相色谱仪依据ASTM D5623 检测汽油中的含硫化合物
Abstract:
依据ASTM D5623，采用Agilent 7890A 气相色谱仪配置355 双等离子体硫化学发光检测器，检测汽油样品中的含硫化合物。355 SCD 线性，等摩尔响应，可提供从0.1 至10 ppm 的线性范围，烃类和硫峰的共流出不干扰检测器的测定。汽油中含硫化合物的检测限可低至20 ppb，且在汽油样品分析中，无淬灭现象。
Sulfur components in gasoline samples are detected utilizing ASTM D 5623 with an Agilent 7890A GC configured with Agilent 355 dual plasma sulfur chemiluminescence detector (DP SCD). The 355 SCD response is linear, equimolar, and provides a linear range from 0.1 to 10 ppm. The coelution of hydrocarbon and sulfur peaks does not present a problem for the detector. The detection limits of sulfur compounds in gasoline are down to 20 ppb, while
no quenching was found in the gasoline sample analysis.
