Description
分析に先立って、HPLC純度のTHFの中にポリマーを溶解させた。その濃度は3mg/mLである。いずれの場合においても、安定化のために1mg/mLのBHTを添加した。溶解時間は、室温で16時間、次いで50℃のオーブン中で4時間、次いで室温で48時間であった。加熱処理の前後に、手で軽く振盪させてポリマー溶液を撹拌したが、そうでないとしても、いかなる点でも、機械的な均質化は一切行わなかった。ポリマーの高分子量粒子を除去してしまわないように、濾過は省略した。AF4チャンネルには、再生セルロース膜(カットオフ指示(cut−off mandate):10kg/molPS)を備えた。
