Abstract

PURPOSE:To realize quick regulation of flow rate while enhancing the work efficiency by finely regulating the cock of an ion exchange column having a chip for uniforming dripping liquid rate fixed at the tip thereof, fixed using an electronic metronome producing a tempo tone previously calibrated with respect to the flow rate. CONSTITUTION:An ion exchange column 1 is filled with an ion exchange resin 2 and stuffed, at the upper and lower ends thereof, with adsorbent cotton. A column cock 5 is provided on the forward end side of the column inserted with a micropipet chip 6 for dripping a liquid uniformly. Dripping rate of liquid from the chip 6 can be regulated by regulating the column cock 5 to constrict the channel of aqueous solution 3 having permeated through the resin. An electronic metronome has variable tempo and the period of tempo tone is varied by means of a tempo setting dial. The column cock 5 is regulated finely so that the dripping rate of liquid matches the tempo tone of the electronic metronome.

By the way, ion exchange columns usually have a non-uniform shape, and it is difficult to uniformly pack the ion exchange resin. The amount of liquid that flows out is taken one by one into a measuring container such as a graduated cylinder, and the amount of liquid per fixed time is measured using a stopwatch to carefully adjust the flow rate, and the flow rate is adjusted in real time. Since it is impossible to do so, even a skilled person takes a long time, and it takes about 5 hours to adjust the flow rate of, for example, 10 ion exchange columns.

According to the present invention, the tempo sound of the electronic metronome is calibrated against the drop velocity of the reference column whose flow rate has been adjusted in advance, and the amount of the droplet attached to the tip of the ion exchange column is made constant. By finely adjusting the column cock so that the drop velocity from the tip for the electronic metronome can match the tempo sound of the electronic metronome, the flow adjustment time can be significantly shortened, and both hearing and vision can be used. As a result, there is little fatigue, and even beginners can make adjustments in a short time.

An ion exchange column for reference whose flow rate is adjusted is prepared, the tempo sound of the electronic metronome is adjusted to the drop velocity (flow rate) by changing the drop velocity of the droplet, and the drop velocity of the drop and the tempo sound of the electronic metronome are adjusted. Check the relationship with the cycle. Based on the obtained result, the tempo setting dial may be calibrated with the drop velocity. Next, after the absorbent cotton and the ion exchange resin are packed in the ion exchange column 1 whose flow rate is to be adjusted, a micropipette tip 6 for keeping the amount of the dropped droplets constant is inserted into the tip of the column. Then, the pure water or the aqueous solution 3 is put into the ion exchange column, and the dial of the electronic metronome is adjusted to the flow rate to be set. Then, the column cock 5 is finely adjusted so that the speed of the liquid drop falling from the chip of the column filled with the ion exchange resin matches the tempo sound of the electronic metronome.
