- You are performing a separation experiment with gas chromatography and notice that your peaks have overlapping elution times. Provide three possible approaches you could take to improve the resolution of the peaks. Explain how these changes would provide a higher resolution using the resolution equation. Which of your listed approaches would be the most cost effective?

Gas Chromatography- Mass Spectrometry
If the chromatographic elution peaks in the sample are far apart
and analysis takes a relatively lon time, should you increase or
decrease the column temperature program to improve analysis time?
Explain your reasoning.

Set up a table and compare and contrast these
4-chromatographic/separation techniques (Gas Chromatography, Liquid
Chromatography, Electrophoresis, Size Exclusion Chromatography).
Make sure to include what characteristic the separation is based
on, the mobile phase, the stationary phases, and an available
detection method for each technique. Thank you!

You compare the performance of multi and one dimensional
chromatography on separation medium that are the same size. Why
might you want to do multi dimensional chromatography instead of
one dimensional chromatography in this situation?
