How to Establish RRF in Analytical Method Validation | HPLC RRF Calculation with Example

Learn how to establish RRF (Relative Response Factor) in Analytical Method Validation using HPLC, with a simple step-by-step calculation and practical example. In this video, you will learn: ✅ What is RRF? ✅ Why is RRF required in impurity analysis? ✅ How to establish RRF using the slope ratio ✅ API vs impurity calibration curve ✅ RRF calculation with a numerical example ✅ How to interpret RRF ✅ Common mistakes while calculating RRF ✅ Important points for Analytical Method Validation Example: API slope = 10,000 Impurity slope = 7,500 RRF = 7,500 / 10,000 = 0.75 ⚠️ Always follow the calculation convention, acceptance criteria, approved analytical method, SOP and validation protocol applicable to your product. This video is useful for Pharmaceutical QC, Analytical Method Validation (AMV), HPLC analysts, Quality Control professionals, QA professionals, and students preparing for pharmaceutical analytical interviews.
