Challenge Problems

Push your limits with challenges.

Question 1

A mixture of unknown compounds is analyzed by GC-MS, resulting in overlapping peaks that affect the accuracy of quantification. Discuss the steps you would take to resolve this issue and ensure accurate identification.

💡 Hint: Think about how adjusting conditions might improve separation.

Question 2

You are provided with a mass spectrum of an unknown compound showing significant background noise along with the signal peaks. Outline the potential causes of this noise and how you would minimize it to obtain a clearer spectrum.

💡 Hint: Consider what might interfere with clean peak observation.
