    Abstract: PROBLEM TO BE SOLVED: To obtain a medicine or an agrochemical (intermediate), by treating a specimen solution containing an ionic surfactant and an organic compound capable of forming an ion pair by using a specific ionic chromatography under a specific condition. SOLUTION: A solution consisting essentially of an organic compound capable of forming an ion pair and an ionic surfactant is separated from a specimen solution containing the ionic surfactant and the organic compound by using an ion pair chromatography using a solvent containing an excessive amount of the ionic surfactant as a moving phase. Then the excessive amount of the ionic surfactant is removed from the separated solution and the organic compound is separated by solid phase extraction. Preferably, after the organic solvent is removed from the separated solution, a strong electrolyte is added to the solution, the excessive amount of the ionic surfactant is precipitated and the precipitate is separated and removed to remove the excessive amount of the ionic surfactant.
