    • A highly reliable hydrophilic sample for analysis of dioxins suitable for analysis through a bioassay method is prepared from a hydrophilic solution of dioxins simply and in a short period of time. A preparation method for a sample for analysis of dioxins includes: supplying a hydrophobic solution of dioxins to a latter column (22) filled with a silica gel-based filler (22a); supplying to and passing through the latter column (22) supplied with the hydrophobic solution a hydrophobic solvent; supplying to and passing through a solvent substitution column (30) filled with an alumina-based filler (30a) the hydrophobic solvent passed through the latter column (22); supplying to and passing through the solvent substitution column (30) a hydrophilic solvent capable of dissolving dioxins from a second solvent supply part (70) in a direction opposite to the direction of the hydrophobic solvent passed through the solvent substitution column (30); and acquiring the hydrophilic solvent passed through the solvent substitution column (30).
    • 通过生物测定方法分析适用于分析二恶英的高度可靠的亲水性样品由简单且短时间内的二恶英的亲水溶液制备。 用于分析二恶英的样品的制备方法包括:将二恶英的疏水性溶液供给到填充有硅胶基填料(22 a)的后一柱(22); 供应并通过供给疏水性溶液的后一柱(22)疏水溶剂; 供给并通过填充有氧化铝基填料(30A)的溶剂置换柱(30a),所述疏水性溶剂通过后一柱(22); 向所述溶剂置换柱(30)供给和通过能够以与通过所述溶剂置换塔(30)的疏水性溶剂的方向相反的方向从第二溶剂供给部(70)溶解二恶英的亲水性溶剂。 并获得通过溶剂置换柱(30)的亲水性溶剂。
