The P 0 4 Polariter
POLAROGRAPHY is α c o m p a r a t i v e l y n e w technique o f f e r i n g vast possibilities in the field of chemical analysis, i n o r g a n i c a n d o r g a n i c . The m e a s u r e m e n t of d i f f u s i o n current in a w e l l d e f i n e d electrolytic process makes it possible to d e t e r m i n e the u n k n o w n c o m p o n e n t in concentrations d o w n to 1 0 4 mol per liter or less.
