Methods and findings in experimental and clinical pharmacology, 1986
The definition of mean residence time in the strict sense of mathematical statistics is deduced. It is demonstrated that the area-normalized concentration time curve is an estimate of the probability density function for residence times of drug molecules in the pharmacokinetic system, provided that the area under the concentration-time profile is ...

Residence Times in Pretreatment
Journal AWWA, 1975This article reviews standard chemical engineering residence‐time analyses methods that deal with effects of compartmentation in mixing systems and techniques for quantitative evaluation of mixed‐flow, plug‐flow, and dead‐space fractions.

Determination of residence times and residence time distributions by the integrated pulse method
The International Journal of Applied Radiation and Isotopes, 1968Abstract It is well-known that residence times and residence time distributions of complicated industrial systems can be determined with the aid of radioactive tracers. Most of the methods in use require accurrate determination of the amount of activity which is injected into the system and good calibration of the detecting equipment.
