Question 1.
What is a calibration curve?
Show hintHide hint
Think about how we can use a graph to show this relationship.
Question 2.
Name one operational mode in gas chromatography.
Show hintHide hint
Recall the two terms discussed during class.
3Question 3.
What does a calibration curve show?
- Relationship between voltage and mass
- Relationship between concentration and peak area
- Relationship between time and temperature
Show hintHide hint
Think about what is being plotted on the axes.
4Question 4.
True or False: Systematic errors are random and inconsistent.
- True
- False
Show hintHide hint
Recall how we defined systematic errors in class.
Question 5.
During your gas chromatography analysis, you find that the calibration curve has a slope of 0.1 and an intercept of 200. Discuss what this indicates about your calibration and how you might improve its reliability.
Show hintHide hint
Reflect on the importance of the slope value in calibration.
Question 6.
You are tasked with finding the concentration of a biologically active compound in a sample that could exhibit systematic loss during analysis. Outline a systematic approach for calibrating this compound to ensure accuracy.
Show hintHide hint
Consider why consistency throughout calibration is key.
