Challenge Problems
Push your limits with advanced challenges
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.
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.
