Update After sitting for 8 days, TE has developed a little more. Still not what I'd expect from the conductivity drop. I sent samples to Frank Key.
Fingers crossed. I might have to revise everything I think I know. That's a scary thought. LOL I might have to develop a taste for crow pie, ey? But however it turns out..that's how it's gonna be. ode [cringe] At 10:28 AM 11/24/2003 -0500, you wrote: >There actually is no point at which tyndall starts showing up. It is a continuous process, and if I remember right changes by the 3rd power of particle size. So as you get smaller the tyndall goes down very rapidly.
