This confirms what I said previously. LVDC produces higher ionic content and smaller particles than HVAC. That site rates collidal silver by the amount of colloid it contains, so they rate the HVAC higher. However almost everyone here will dispute that higher colloid content means better EIS, and the HVAC produces larger particles as well as higher percentage of colloid, so it can be argued either way depending on if you consider high colloid content a plus or a minus.

Really? One of your references you listed, the SilverColloids-s.pdf, on page 25, states:

AC- or DC produced solloidal silver
In the marketplace today are found advertisements for
colloidal silver products produced using alternating current
[AC] and direct current [DC] or devices to make colloidal
silver.  The DC-produced colloidal silver products that we
have tested for this study had the highest value of ionic
[dissolved] silver present [up to 17 ppm] and did not have
highly rated colloidal silver.  All of the highest 4-star rated
colloidal silver products tested were produced utilizing the
AC process.

The answer is DC.
If you didn't know that, you are woefully behind in your understanding
of CS creation and your research.
