Worksheet: Theoretical Plates

In this worksheet, we will practice calculating the number of theoretical plates from a chromatogram and relating the equivalent height value to resolution.


If a compound has a retention time of 5.30 minutes with a baseline width of 0.64 minutes on a 2.0 m silica gel column, what is the average height of a theoretical plate?

  • A1.8 mm/plate
  • B29 mm/plate
  • C0.24 mm/plate
  • D15 mm/plate
  • E2.7 mm/plate
