Determination of hexane in the acid cluster of caprolactam by high performance liquid chromatography with indirect photometric detection
高效液相色谱-间接光度检测法测定己内酰胺酸团中的正己烷含量

An indirect photometric detection method for the determination of hexane in the acid cluster of caprolactam by high performance liquid chromatography was developed.Ultraviolet(UV) absorption background reagents were added in the mobile phase,and the hexane,non-absorption in ultraviolet region,was directly determined by a UV detector.The effects of the mobile phase composition,species and concentration of the background reagents etc.on the analyzed results were studied.The optimization of the separation was ...
