Abstract: PURPOSE: To quickly analyze a wide range of drugs by combinedly arranging an anion-exchange column, a reversed phase column, and a cation-exchange column in this order and selecting column media, carrier liquid, and identifying means. CONSTITUTION: Solvents and carrier liquids in three tanks 19-21 are sent to a sampling device 28 through a selection valve 25 and reach the entrance of a four-way valve 31 through an eight-way valve 30 and a preceding-stage column 15 after the device 28 collects a fixed amount of sample. On the other hand, a carrier liquid of a prescribed concentration in a liquid tank 23 reaches the valve 31 through a pump 24 and successively carries a liquid containing the sample through an anion-exchange column 12, a reverse phase column 13, and a cation-exchange column 14 in a housing 11. The columns 12-14 are filled up with prescribed materials and the effluent from the column 14 is scanned with ultraviolet rays from a scanning ultraviolet-ray detector 35. Acquired information is inputted to a computer monitor 37 and the kinds and amounts of drugs are decided. The analyzed results are printed by means of a printer 38.
