Yes, you are right except in regards to stability. Whilst the silver can't disappear, it can plate out on to the sides of the container, or flocculate and settle out. Being a manufacturer of CS, I probably have different expectations of a quality CS than most users, to me stability is paramount as the label must reflect the contents of the bottle even after sitting on the shelf for a year or more. I also need to be prepared for some authority testing the contents for purity.
However, I am the first to say that it is practically impossible to make a CS that is not effective, no matter how simple the generator... I am not one who believes that particle size is of great importance, 1nm or 50nm, it all seems to work... its just that the smaller the particle size the more stable the colloid. I should also note, that when I measure CS I measure the ionic content primarily because that is what I endeavour to produce. Glass bottles are intuitively the best container, but this is not necessarily so. Positive ions (cations) will plate out onto glass, and inert plastics are probably a better choice. Pure CS should not be light sensitive. Apart from electron microscopy, or 20nm syringe filters, there is no cheap particle sizing.

Solution ppm shouldn't typically change, even over long term, as the silver can't just "disappear." However, it can clump into larger particles (due to cohesive forces), rendering it ineffective. It can also combine molecularly with contaminants in the solvent (water) or the container, which makes a good case for using inert (glass) bottles. Also, keep in mind due to light degradation. Particle size can be tested, but not without cost. Btw does anyone know of an inexpensive particle size tester? I think it's lab equipment, not a handheld like a TDS meter. Would appreciate anyone who can either affirm or correct the above information. I Anderson <i...@win.co.nz> wrote: I guess it's a case of what ever works for you! I have 10L of 3 year old CS, slight golden colour, that tests as having the same concentration (22ppm) as the day it was made. And it was made without any stirring at all, apart from the occasional hand stirring during the 2.5 days it took to make it!
