In practical terms, it is not possible to have a purity level higher than 100%. Purity refers to the degree of impurities or contaminants present in a substance, and it is typically measured as a percentage.

In the context of Singapore, if you are referring to the purity of a chemical or a product, it is unlikely that it can exceed 100%. Purity levels are usually expressed as percentages, with 100% representing the highest achievable level of purity, indicating that the substance is completely free from impurities.

However, it is worth noting that the concept of “purity” can vary depending on the context. For example, in certain industries or applications, purity might be measured or expressed differently. If you can provide more specific information or clarify the context, I can try to provide a more accurate response.
