Enter the peak area and the concentration into the Calculator. The calculator will evaluate the Response Factor. 

Response Factor Formula

RF = PA / C


  • RF is the Response Factor ()
  • PA is the peak area
  • C is the concentration

To calculate the Response Factor, divide the peak area by the concentration.

How to Calculate Response Factor?

The following steps outline how to calculate the Response Factor.

  1. First, determine the peak area. 
  2. Next, determine the concentration. 
  3. Next, gather the formula from above = RF = PA / C.
  4. Finally, calculate the Response Factor.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

peak area = 5.678

concentration = 1.2354
