After completing this activity, students will be able to:
- Explain the differences between external standard and standard addition calibration and describe situations when each should be used.
- Give examples of when an internal standard is necessary and describe what types of experimental error it can correct for.
- Calculate the concentration of an analyte given raw data using any of these calibration methods (external standard, standard addition, internal standard).
- Determine which method is most appropriate to utilize when faced with a real world analytical problem.
