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.
Silver billet tip is designed for reactions with halides to generate a mV potential during a potentiometric titration.
Polyethylene (PE) Movable Sleeve
CPS™ technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows proper flow of the liquid, while the PTFE sleeve repels dirt. As a result, pH electrodes with CPS™ stay fresh up to 20 times longer than conventional electrodes.
The HI5148B is a refillable double junction combination electrode. This allows you to choose your fill solution based on method of analysis and the solution can be exchanged if it becomes contaminated.
