Micropore Junction
Most gel-filled electrodes utilize a wick or diffusion style junction. These
junctions allow the sample to diffuse in and the reference gel to diffuse out,
causing a shift in potential. Some samples also react with the silver ion in the
gel, which forms a precipitate. Both of these processes will cause clogging of
the junction, as seen by slower and less accurate response over time.
Beckman Coulter gel-filled combination electrodes have a special micropore
junction that provides better performance compared to traditional gel-filled
electrodes. The micropore junction consists of several small pores in the
actual body of the electrode. This micropore junction is wiped clean each time
the electrode is rinsed. There is direct contact between the sample and the gel,
thus resulting in faster and more accurate readings. Additionally, this
allows the electrode to be stored dry and eliminates the need for a special
storage solution.
