Expert writing Tips

Best practice

When describing a process aimed at reducing impurities, clearly state the initial and target "level of impurity" to demonstrate the effectiveness of the process.

Common error

Avoid using "level of impurity" without specifying what the impurity is. For instance, instead of stating 'the level of impurity was high', specify 'the level of lead impurity was high'. This adds crucial context and avoids ambiguity.
