The retention time is calculated according to the following equation:
What is the retention time for Peaks A and B below if the chart speed was 2 cm/s?
Answer
The center of peak A is at approximately 6.5 cm. Thus, the calculation is 6.5 cm/2cm/s = 3.25 s = 3 s.
The center of peak B is at approximately 13.5 cm. Thus, the calculation is 13.5 cm/2 cm/s = 6.75 s = 7 s.
