PCB異性体分析 PCBsのGC分析用カラム →DB-5及びHT8が多く使用されている。 HT8は8%フェニル相当の微極性カラムであ り、その固定相に、カルボランが化学結合され ていることを特徴とし、従来の微極性カラムで は分離しえなかった異性体を分離している。 しかし、 HT8においても主要な異性体であ る#44、#74、#101、#118、#105 等の分離が不 十分である、#149のフラグメントイオンが#77に 重なるなどの問題点があった。 そこで、 新規なキャピラリーカラムである HT8-PCB を用い、PCBs全209異性体の分離条件 を検討するとともに、各異性体の溶出順位の決 定を行ったので報告する。 試 薬 PCBs各209異性体の標準物質 Accu Standards Inc.
