Description
The manufacturer states:
High-purity gold dispersion, 30 ppm
Colloidal gold is required and produced only in very low concentrations. Consequently the solution remains almost colourless and therefore differs from the often offered reddish-tinted solutions. Because the release of gold from the electrodes in this range is very difficult to determine, the stated concentration can only be an approximate value. Colouration, among other factors, always depends on concentration and particle size. Higher concentration/larger particles = stronger colour. The differences in particle size that lead to discolouration are usually very small, so a slight reddish tint should not be taken as an indication of reduced quality. It should also be noted that chemical production processes can cause colouring due to residual compounds.
