Description
分離膜10は、例えば再生セルロース(RC)やポリエーテルスルホン(PES)など、複数の細孔を有する半透膜の表面に、陽イオン交換性又は陰イオン交換性を有する官能基が修飾されたものである。
この実施例では、フォーカシング及びリラクゼーションが終了した後の送液ポンプ14の動作速度は一定に制御され、MFC26によって排出ポート24から排出されるキャリア流体の流量、すなわちクロスフローの流量が制御される。これにより、出口ポート6から流出するキャリア流体の流量が一定になる。なお、排出ポート24からの流路上に、MFC26に代えて流量計を設け、その流量計の検出流量に基づいて、出口ポート6から流出するキャリア流体の流量が一定になるように、送液ポンプ16の動作が制御されるように構成されていてもよい。
