Question 1.
What phases are involved in Gas Chromatography?
Show hintHide hint
Think about what stays fixed and what moves.
Question 2.
What is the purpose of using a gas as the mobile phase in GC?
Show hintHide hint
Recall how gases behave in chromatography.
3Question 3.
Which phase remains fixed in Gas Chromatography?
- Mobile phase
- Stationary phase

Show hintHide hint
Remember which one stays put.
4Question 4.
True or False: Gas Chromatography can be used to separate and analyze non-volatile compounds.
- True
- False
Show hintHide hint
Think about the properties of the compounds involved.
Question 5.
Design a Gas Chromatography method for analyzing a complex environmental sample containing multiple volatile compounds. Include the choice of mobile and stationary phases, type of detector, and considerations for ensuring accurate results.
Show hintHide hint
Think about the characteristics of the solutions you're working with.
Question 6.
Critically assess how pressure changes in a gas chromatography system may impact the separation efficiency of compounds with similar boiling points.
