If I have an opening on the side of my electrochemical cell, I'm wondering if I can use this to insert a reference electrode. It is normally used to insert an L-shaped tube where you place the reference electrode, and is connected to luggin capillaries. I'm wondering if we can take out the entire connection with the capillaries and replace it with only the reference electrode (sans capillaries). This is in a 3-electrode system, so if I could insert the counter electrode in this way, that would work too. In my setup, I cannot do this with the working electrode.
From what I've read, it's good practice to not have the reference electrode vertical because of bubbles on the bottom of the frit (so most tilt it slightly), but I haven't read anything about a sideways electrode.
