When doing the settling test, what should you do if clumping of the particles occurs?
-
Replace the particles
-
Replace the vehicle
-
Demagnetize the bath
-
Demagnetize the suspension in the tube
That's Correct!
It's Wrong!
When clumping of the particles occurs during the settling test, it indicates that there may be magnetic forces at play. Demagnetizing the suspension in the tube helps to eliminate these magnetic forces, allowing the particles to settle properly. This ensures accurate and reliable results in the settling test.
