Challenge Problems
Push your limits with advanced challenges
You have a complex mixture of volatile and non-volatile compounds. Describe how you would set up a chromatography experiment to effectively analyze both types, including any steps you would take to dynamically control the process.
💡 Hint: Think about the characteristics that each type of compound has in relation to their phase preferences.
The results from your chromatography analysis show overlap in peak retention times for two different analytes. Discuss possible strategies to resolve this issue without reanalyzing the samples.
💡 Hint: Identify how changing each parameter can influence separation of analytes!
