Study Notes
Spectrophotometry
- A turbid sample is unsuitable for analysis using a spectrophotometer.
- Turbidity in a sample interferes with the transmission of light, affecting the accuracy of absorbance readings.
- Clear or transparent samples can be analyzed using a spectrophotometer.
- The primary reason a spectrophotometer cannot analyze a turbid sample is that it scatters light, preventing precise measurements.
- A limitation of using a spectrophotometer is that it requires clear or transparent samples for accurate results.
