The potential of alkylammonium ion-bonded silica stationary phases for effective and simple pretreatment for determination of polychlorinated biphenyls (PCBs) in mineral oil samples is presented in this paper. The separation between PCBs and aliphatic hydrocarbons by normal phase chromatography was improved by using the alkylammonium ion-bonded silica stationary phases instead of alkylamine-bonded silica or other polar stationary phases. The number of alkyl residues bonded to the nitrogen atom was also an important factor of the separation.
本文介绍了烷基铵离子键合硅胶固定相在矿物油样品中多氯联苯（PCBs）测定的有效且简单预处理方面的潜力。通过使用烷基铵离子键合硅胶固定相而非烷基胺键合硅胶或其他极性固定相，正相色谱法中多氯联苯与脂肪烃之间的分离得到了改善。与氮原子键合的烷基残基数量也是分离的一个重要因素。
