English term or phrase: isocratically
The recemic was resolved with chiral normal phase HPLC using a semi-preparative column, eluting isocratically with hexane/isopropanolなんですが、isocraticallyの意味は何でしょうか?辞書になく、検索しても、いまいち意味がつかめません。 よろしくお願いいたします。

移動相に一定組成の用いる均一濃度溶離(Isocratic elution)では、固定相に対する保持力が異なる成分の分離の際に長時間要したり、ピークが拡がることがあります。このような場合には、移動相の組成を連続的に変化させる勾配溶離(Gradient elution)用いられます。ピークが拡がってしまう時には、移動相の有機溶媒の組成比を上げ、溶離力を上げていくことにより試料の拡散によるピークの拡がりを抑えたピークを得る事が出来ます。
