Percent Recovery Guide

What is Percent Recovery?

Percent recovery measures the efficiency of an analytical procedure: \text{Recovery} = \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \times 100\%

It indicates how much of the target analyte was successfully recovered from the sample.

Recovery Standards

  • Excellent Recovery (95-100%): Outstanding method performance
  • Good Recovery (80-95%): Acceptable for most analytical methods
  • Fair Recovery (70-80%): May need optimization
  • Poor Recovery (<70%): Method requires significant improvement

Common Procedures and Expected Recoveries

  • Liquid-Liquid Extraction: 70-90%
  • Solid Phase Extraction: 80-95%
  • Crystallization: 60-85%
  • Distillation: 75-95%
  • Column Chromatography: 65-90%

Factors Affecting Recovery

  • Sample matrix complexity
  • Analyte stability and volatility
  • Extraction/separation efficiency
  • Instrumental limitations
  • Operator technique and experience
  • Environmental conditions (temperature, pH)
