Description
離度合を生成する必須の操作条件が見いだされた。これらの多段カラム連続的なクロマトグラフィー法は、古典的バッチクロマトグラフィーにおけるある種の制約を克服し、例えば、増強された生産性、より低い溶出液組成およびより高い確実性を有する結果、より低い最終精製コストをもたらす。
いる)においてより完全に記述されている。この非定常状態法は、入口と出口の出入口がすべて同時には切り替えられない点でSMB法とは異なる。ゾーン間のカラムの分配は、ラインが種々の時間に切り替えられるので期間中で同じに止どまらず、カラムの配分はそれに応じて異なる。この方法では、与えられたカラムの数について配置の数には制限がないので、SMB法に比較してより大きな度合の柔軟性を非定常状態法に与える。クロマトグラフィーによる分離の間のカラム部分によって表される特定のゾーンの平均の長さの変化についての可能性は、より少ないカラムを用いることによる効率の増強、固相と溶媒の量の減少、およびより高純度の収量の増大をもたらすことができる。
エステル;アセトン、ブタノン、イソプロピル−メチルケトンのようなケトン(C1−C10);ジエチルエーテル、ジイソプロピルエーテル、tertブチルメチルエーテル、テトラヒドロフラン、ジオキサンのようなエーテル(C1−C10);塩化メチレン、クロロホルム、クロロベンゼン、フッ素化アルカンのようなハロゲン化炭化水素(C1−C10);トリフルオロ酢酸;ジメチルホルムアミド;ジメチルアセトアミド;およびアセトニトリル、およびそれらの組み合わせ物からなる群から選ばれる。ある態様では、移動相は極性溶媒、好ましくはC1−C6アルコール、より好ましくはメタノールである。
