Good morning, Wayne,
I am all confused about the uS/ppm issue.
With the help of many in the list, including you, I have learned very much
and I have managed to make what I consider very good quality EIS. From what
I have read before, well made EIS is very stable after a couple of days, and
it will last a long time, some of the more knowledgeable ones in the list
even said it will last "for years".
I meticulously have registered the V/mA readings every 15 minutes or every
30 minutes, depending on the length of the process in any case, in every
batch I have made since I started many months ago. After I finish, I
introduce the data in the Faraday Equation sheet you guys gave me at the
beginning, in order to get an estimate on the ppm concentration for every
batch, which I try to maintain around 15 ppm allowing for some slight loss
later.
I proceed to bottle it, label it with the date and ppm info, and store it
and share it with family and many friends. I am making an average of 1.5
liters/day. A couple of months later there has been no visible change in the
cristal clear color, no sediments, no apparent changes in flavour. After
recycling many times, some containers (transparent, no color, soda pop
bottles) start getting a slight amberish hue, which I assume it means a
little of the silver depositing on the walls and bottoms of them, which I
assumed meant a very slight, negligible loss of the silver contents.
The only sophisticated method I have in order to guess what I made is to
maintain a very low mA all along the process, which allows for only a little
cathode cleaning during the last third of the process, and gives me cristal
clear EIS, no amber color hue and practically no Tyndall effect (both of
which I assume mean very small colloidal particles), no residues, and the
conductivity mA readings which are later fed into the Faraday equation
sheet.
Now I am all confused. Even Ode said that the larger the batch, the greater
the changes. What am I getting and how can I give my EIS to others not
knowing if will be of any effect after some time?
Thank you very much.
Carlos

Evening Julius,

You are going on the idea that uS is true ppm.
You have taken water and silver, added them together, and bottled it, put a
lid on it, ......... how do you think it got out?
I have used an EC meter but still depended on calculated ppm.
I have also worked with reasonably expensive EC sensors with an analog
output.
The more money you spend, the better the instrument.
Don't bet your life on a low cost EC meter.
After all, ppm is a weight, not a charge. EC meters are not true weight
devices. They are reading ions that tend to change, interactions between
elements, and lots of other things enter into the picture.
When I weigh a specific amount of chemical, add that to a specific amount
of water, I know the ppm. I never look back and never worry about it
again.
I would be interested in what point you are trying to understand or to
prove?
You are getting into laboratory techniques and without proper instruments,
you are doomed to failure, or confusion, or lost sleep, or plain old
worry.
Wayne
