If you know the approximate ppm, then the intensity of the Tyndall can
give you an idea of the average particle size. Intensity goes up
linearly with the ppm, and to the 3rd power (if I remember right) of the
particle size.

Can you learn anything from Tyndall effect beside the fact that there are

They are used to check the Tyndall in your EIS.

Just to share some information, Walmart sells a very inexpensive laser
for under $2 (that is what I paid). It is in their pet area. It's called the
"Laser Pet Exerciser." I believe they make them for cats. I purchased 2 of
these last month - they actually come with an extra set of button batteries
(unit takes 3 of these). Seems to work fine. Has a very sturdy switch and is
attached to a keychain.
