## compartmental analysis

https://doi.org/10.1351/goldbook.CT06818
Mathematical process leading to a model of transport of a substance in terms of compartments and rate constants, usually taking the form $C=A\ \text{e}^{-\alpha\ t}+B\ \text{e}^{-\beta \ t}\text{...}$ where each exponential term represents one experiment. $$C$$ is the @S06072@; $$A$$, $$B$$,… are proportionality constants; $$\alpha$$, $$\beta$$,… are rate constants; and $$t$$ is time.
