 (pə-tĕn′shē-ŏm′ĭ-tər)
n.
1. A three-terminal resistor with a manually adjustable center connection that adjusts the resistance between the end terminals and the center, whose uses include controlling the volume of an amplifier. Also called pot3.
2. An instrument for measuring an unknown voltage by comparison to a standard voltage.

Some of these methods require expensive apparatus and are time consuming, whereas determination of silver(I) ions with potentiometric methods are both low cost and simple [16], Especially potentiometric systems combined with flow injection analysis systems can be used in potentiometric analysis due to their great properties such as working in a small sample volumes, continuous washing of detector, simple instrumentation and wide linear working range [17-19].
A Titraplus potentiometer with a specific electrode for lead and Calomel electrode as reference (Tacussel, model XS 300) was used for the potentiometric analysis. H-NMR spectra were taken by 500 MHz Bruker (Germany) instrument, the copolymers were freeze-dried and the organic component dissolved in CDC13 prior to NMR analysis.
The degree of incorporation of acid groups inside and on the surface of the latex particles was evaluated by potentiometric analysis in an organic medium.
