对酞内酰胺苯甲酰氯柱前衍生反应高效液相色谱法检测痕量脂肪醇
High Performance Liquid Chromatographic (HPLC) Determination of Trace Aliphatic Alcohols by Pre-column Derivatization with 4-(2-phthali-midyl) Benzoyl Chloride (PIB-C1)
【摘要】 <正> 在某些高纯度试剂中,痕量的醇是一种杂质,其含量应受到限制。为此,需要研究检测痕量醇的方法。众所周知,脂肪醇在远紫外区吸收较弱,在205~650nm范围则无吸收,因而,应用HPLC紫外检测手段很难发展直接测定痕量醇的分析方法。应用
【Abstract】 A sensitive method for the PIB-C1 determination of trace aliphatic alcohols by using HPLC is described. The conditions of reaction, separation and quantitative analysis were studied. The molar absorption coefficient of the C1-C8 alcohol derivatives were measured. The detection limits were 0.97-19. 23pmol.
