Objective Performing the Conductivity Test Analysis on PVOH Films Description This experiment was conducted to measure the conductivity of a PVOH film cross-linked with glutaraldehyde at different time intervals. Cell constants: 0.4663 (orion versa star) 0.479 (orion 5 star) was the instrumental constraints for this experiment. Data Add data and results here... Data Summary 100 ppm chloride (Cl-) initially at 18.2 ml with probe insertion and 100 ppm (Br-) ion solutions, initially at 29.0 ml of probe insertion, were used on either side of the film. Also HPLC grade water was used.
