PPM, meaning parts per million, is best used to describe the quality of performance or concentration of a substance in a larger mixture. This could be used to describe contents in water, a supplier's defective rate, etc. It is technically a dimensionless measure illustrated as a percentage an...
Going through a basic PPM calculation by volume or by mass will help to cement the concepts you need to understand. For mass, imagine you have 0.98 liters of water with 0.2 g of salt dissolved in it, noting that 1 L of water = 1 kg of mass, so the total mass in the example is ...

Colloids are simply particles suspended in water, meaning they do not dissolve, and silver colloids are the insoluble particles (Ag) and oxides (Ag2O) which are often produced by previous colloidal silver generators. Generally these particles range from 1-100 microns in size (1 micron = 1000 nm...
