Worse than that...the particles in a TEM photo were MADE by preparing
the sample and were never in the water.

smallest particles. To make CS that fast would require a
much higher current.. and consequently produce larger
particles. I'd like to see a proper particle size
report, not that TEM stuff on their site. (This report
explains why TEM images for colloidal silver are
extremely misleading...

Thank you for this link. It cleared up a lot of
misconceptions for me about ionic versus colloidal silver
and how poor TEM photos are at showing the true proportions
or distribution of particle sizes.
The drying process, that is an essential part of the sample
preparation, alters the sample in rather arbitrary and
uninformative ways.
It is a bit like taking inventory of a house by burning the
house down and then sifting the ashes.
TEM is really the wrong tool for the task of analyzing
something so delicate and complex as silver water.
