In the Thermo Fisher application note about wine analysis (Lesson 3), the following
chromatogram was collected of nine components of wine. If peak 3 has a retention time of
3.15 minutes and a peak width of 0.070 minutes, and peak 4 has a retention time of 3.24
minutes and a peak width of 0.075 minutes, what is the resolution factor between the two
peaks? [Hint: it will help to review Lesson 2 for this question.]
