Response optimization is used to determine the optimal conditions for recovery of a sample for HPLC. The three factors are: A- Solvent (Hexane or Ethyl Acetate); B- pH (8 or 10); and C- time (30 or 60 minutes). The two response variables are Recovery and Variance. What are the optimal conditions for this process?
