Destruction Degradation and Arrhenius Equation.

Created: Sep 28, 2022 04:52 PM  |  Last Modified: Jun 10, 2023 1:52 PM (2137 views)

I have stability data at three different temperatures (5C, 25C and 40C) and I am trying to use Arrhenius model to predict the estimate of impurity at 25C after 24 months. What model should I use in JMP?

Arrhenius rate goes into different degradation models. Following is a screenshot of one model. But this is a type of repeated measures degradation (use "Repeated Measures Degradation" tab in the launch dialog of the Degradation platform). I see practitioners usually treat stability data as repeated measures degradation data. So I am not sure why you wrote Destruction in the title. But JMP's standalone Destructive Degradation (under Analyze menu, Reliability/Survival sub-menu) platform provides similar models as well.
