Purifying and Concentrating Chemicals Beyond 96% Purity

The process of purifying and concentrating chemicals, such as methamphetamine, to high purity levels (above 96%) is extremely difficult and costly. This challenge is highlighted by the significant jump in difficulty from 96% to 99% purity. The issue is not just about filtering out impurities, but also about overcoming the limitations of chemical reactions and separation processes.
