There are two types of sensors available for performing a chloride titration with silver nitrate. The first type includes solid-state sensors, such as silver or chloride ion selective electrodes (ISEs), and the second are metal electrodes, such as the silver billet electrode. ISEs are expensive and can be problematic if left in solution for a long time due to the softening of the compressed sensing pellet. The silver billet is economical and does not soften with extended periods of time in solutions making it ideal for high throughput sampling.
