Question 1.
What does sensitivity refer to in chromatography?
Show hintHide hint
Think about how small a quantity can be identified.
Question 2.
What is one reason calibration is important?
Show hintHide hint
Consider the relationship between measurements and standards.
3Question 3.
What is the purpose of calibration in chromatography?
Show hintHide hint
Think about how we relate our measurements to something established.
4Question 4.
SIM mode increases sensitivity by focusing on specific ions.
- True
- False
Show hintHide hint
Recall the difference in focus between SCAN and SIM.
Question 5.
A chemist performed a series of dilutions on a sample, but still received inconsistent peak responses in chromatographic analysis. What steps can they take to improve the situation?
Show hintHide hint
Think about what might cause variability in detection and how to standardize it.
Question 6.
With a newly developed method of chromatography, it has been reported that sensitivity is low for certain compounds. What factors could be contributing to this issue and how would you evaluate potential solutions?
Show hintHide hint
Consider the different stages of the chromatography process where problems can arise.
