Purity can only be measured for a particular lot, which can be calculated based on the iron content determined for that lot. The ratio of the experimental content and the theoretical content, expressed as a percentage will be the purity of the particular lot. For example, an experimental result of 68.6 iron corresponds to a purity of 98.1.
