Paragraph starter
The development of analytical methods can be significantly improved through systematic optimization, as demonstrated by the application of Analytical Quality by Design (AQbD). This approach allows for the identification of critical parameters that not only ensure method robustness and accuracy but also minimize environmental impact, such as reducing solvent consumption. For instance, a study optimizing an RP-HPLC method for drug estimation found that AQbD led to a more sustainable process with reduced waste, aligning with green chemistry principles and supporting efficient quality control.
