Enter the total change in absorbance and the total time (min) into the Delta Absorbance Per Minute Calculator. The calculator will evaluate the Delta Absorbance Per Minute. 

Delta Absorbance Per Minute Formula

The following two example problems outline the steps and information needed to calculate the Delta Absorbance Per Minute.

APM = dA / T

Variables:

  • APM is the Delta Absorbance Per Minute (absorbance/min)
  • dA is the total change in absorbance 
  • T is the total time (min) 

How to Calculate Delta Absorbance Per Minute?

The following steps outline how to calculate the Delta Absorbance Per Minute.


  1. First, determine the total change in absorbance. 
  2. Next, determine the total time (min). 
  3. Next, gather the formula from above = APM = dA / T.
  4. Finally, calculate the Delta Absorbance Per Minute.
  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.

total change in absorbance = 5

total time (min) = 3

APM = dA / T = ?
