Abstract
A sensing device for the determination of ions in a thin layer sample (32) comprising: a first (12) and second (14) ion selective electrode, each having a first (16) and second layer (20); the first layer (16) of the first ion selective electrode (12) being a polymeric membrane layer in electrical contact with the second layer (20) of the first ion selective electrode (12), and the first layer (18) of the second ion selective electrode (14) being a polymeric membrane layer in electrical contact with the second layer (20) of the second ion selective electrode (14); the first and second ion selective electrodes being positioned in opposing arrangement such that, the respective polymeric membrane layers are in direct contact with a thin layer sample (32) containing ions, located between the first and second electrodes; and a detector (28) in electrical connection with the first (12) and second (14) ion selective electrodes.
