How can temperature studies provide information about the thermodynamics of retention?

The retention factor is estimated simply as follows. Note that the numerator of the equation (tR – t. 0. ) tells us to subtract t. 0 from the retention time. The retention factor is a measure of the average time a chemical resides in the stationary phase versus the time it spends in the mobile phase. This value can ... Jun 17, 2023 ...
