Again, the smallest particle size measurable is 2 nm, done with the ICP method, there are no other instruments that can measure atoms in water, however it does not mean that they cannot be DETECTED.
The same ICP methods uses a Plasma Arc to "burn" up the particles into larger particles that can then be measured and verified.
Other known chemical tests will not detect anything, which explains the dogmatic stance from certain forum members.
As Gold2live.com explained to me, yes they had other belivers of the products post information that may have been slightly incorrect, however the website has updated information about the particle size.
