+  '''Conductivity of PVOH film'''  
+  
+  *Conductivity of PVOH was measured by using Thermo Scientific and Orion Versa Star.  
+  
+  *The probes were platinium,  
+  
+  *The cell constant for Thermo Scientific was 0.479.  
+  
+  *The cell constant for Orion Versa Star was 0.4663.  
+  
+  *After placing the film between two columns, a solution containing 100 ppm Cl, 100 ppm Br and 100 ppm SO42(as Na+ salts, in to the left column. Place HPLC water to the right column.  
+  
+  *Initial height for left column is 18.2 cm.  
+  
+  *Initial height for right column is 18.7 cm.

+  *Final height of each column was not recorded as there was a leak between the columns.

+  *The conductivity after a week was not recorded because of the leak. The leak also prevent measurement of final height of the solutions in the column.
