【摘要】 开发了一种新的 ０．１～１．０ｍｇ／Ｌ痕量硫的分析系统及方法。方法以 Ａｎｔｅｋ ７０００氧化裂解－紫外荧光定硫仪为基础，通过对进样系统、裂解管、及检测限等方面的改进，使单次分析样品最大进样量增加到 ５０μＬ。方法的检测限达到 ０．１ｍｇ／Ｌ，满足了科研及生产工艺的需要。更多还原

【Abstract】 An improved system and method of 0. 1-1. 0 mg/L trace sulfur detection in light hydrocarbons was developed on the Antek 7000 Pyrolysis UV-induced Fluorescence Sulfur Analyzer. The maximum injection volume was raised to 50μL,after heating the pipeline con- necting the pyrotube and the detection system and using a new design pyrotube. The results showed that the method is good enough to meet the need of the technological research and in- dustrial process with a detection limit of 0. 1mg/L.更多还原
