Show hintHide hint
Think about what happens when two substances are analyzed together.
Question 2.
Define calibration in the context of chromatography.
Show hintHide hint
What do we use to ensure our measurements are correct?
3Question 3.
What does peak overlap in chromatography indicate?
- Improved separation
- Complicated analysis

Think about what overlapping peaks do to your analysis.
4Question 4.
True or False: SIM is used for qualitative analysis.
- True
- False
Show hintHide hint
What does SIM focus on?
Question 5.
You are analyzing a mixture of organic compounds using both SCAN and SIM modes. Discuss how each approach might affect your findings in terms of accuracy and detection limits.
Show hintHide hint
Consider how focus may trade off with broad analysis.
Question 6.
Discuss how the choice of calibration (concentration vs. mass) can impact the reliability of your analysis results in an organic compound investigation.
Show hintHide hint
Think about what factors might change your measurements.
