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)
