A glass capillary of approximately 0.8mm. inside diameter and approximately 10cm. long, filled with alumina and having a pinhole at one end was used as a means of detecting several kinds of mixed ions by suction of sample solution and coloration reagents into the capillary through the pinhole. Limit of detection of metallic ions by various coloration reagents was examined and the present method was found to be far sharper than the paper spot test and the best suited for the detection of a minute amout of ions. The feature of this method may be said to lie in the fact that only a minute amount of sample and alumina are needed and that the procedure is simple and time short.
