Use of a laser/photodiode array detector system to study mass transport across membranes

A new instrument has been developed to rapidly measure the rate of mass transport across interfaces or membranes without the need for sample extraction. This instrument utilizes a pulsed laser as the light source and a photodiode array as the detector, together with a specially designed diffusion ce...

Zusammenfassung:A new instrument has been developed to rapidly measure the rate of mass transport across interfaces or membranes without the need for sample extraction. This instrument utilizes a pulsed laser as the light source and a photodiode array as the detector, together with a specially designed diffusion cell to acquire spatially resolved data.
