Nettet2. mai 2024 · Linearity is important for the analysis of the analyte’s concentration within a defined range. A defined range is important because for each drug the content of the active ingredient as well as the content of potential impurities is not always exactly identical from batch to batch, but can vary slightly, which is why concentrations above and below the … NettetcriteriA for lineArity Linearity is measuring the linear response of the method. The eval-uation of linearity is minimally 80–120% of the product specifica-tion limits or wider. Acceptance cri-teria must demonstrate the method is linear within that range or higher. The following are techniques to demonstrate the method meets
