Question 1.
What is derivatization?
Show hintHide hint
Think about why we need compounds to be stable during analysis.
Question 2.
Why is concentration often preferred over mass in chromatography?
Show hintHide hint
Consider the factors that might cause mass loss.
3Question 3.
What is the main purpose of derivatization?
- To increase stability of compounds
- To decrease detection limits
- To provide broad analysis
Show hintHide hint
Remember, it's all about making compounds easier to analyze!
4Question 4.
True or False: SCAN mode is more sensitive than SIM mode.
- True
- False
Show hintHide hint
Think about what each mode is designed to do.
Question 5.
You have two similar compounds, one stable and one unstable. How would derivatization affect your analysis approach for these two compounds?
Show hintHide hint
Consider the implications of stability in analysis.
Question 6.
If you are analyzing a sample with potential overlapping peaks, what methods would you recommend for clearer results?
Show hintHide hint
Focus on solutions that tackle peak clarity.
