Method for manufacturing an ion-sensitive electrode

摘要

The body of an ion-sensitive electrode is formed from a bulb (32) of an ion-selective material that is transparent to infrared radiation. A glass tube (12) made of material that absorbs infrared radiation is inserted into the bulb, and a source (15) of infrared radiation is focused through the bulb (32) onto the end of the tube (12) on which the bulb (32) rests. The resultant heating causes the tube and the bulb to fuse together, and the portion of the bulb outside the tube is then removed to result in an electrode body (FIG. 4).
