Photoacoustic detection based permeation measurements: Case study for separation of the instrument response from the measured physical process

Photoacoustics, 2018
In a carrier flow based permeation system the measured permeation curve is the convolution of two processes: the intrinsic permeation process and the transfer of the permeated molecules through the measuring system.
