The multiplex circulating loop fill device and method for the microanalysis with ion color layer analysis

摘要

(57) Abstract In order to do fixed quantity microanalysis with ion color layer analysis, the minute ion contaminant the ion color layer analytical instrument and the method before on column of making concentrate. This method after making the sample solution the sample fill loop fill up (26), repeats the fact that it removes, includes the continual step of the multiplex circulation which before makes the separated column concentrate (30) cumulatively at the cumulative quantity of the sample. With each removal step, from the sample fill loop (26) pushing out approximately up to 98% of the sample solution of the known quantity the liquid which predetermined time, was pressurized substantially with constant flow facing toward the sample fill loop (26), is included. After that, this the sample solution of the quantity which is investigated passes the ion-exchange resin column (30), the minute ion contaminant is concentrated in the resin.
