Silver/Sulfide Combination Ion Selective Electrode (ISE) HI4115
The HI4115 is a solid state, combination ion selective electrode (ISE) for the determination of silver (Ag+) or sulfide (S2-) in solution. The silver/silver sulfide sensing pellet produces a potential change due to the ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable polyetherimide (PEI) body. The HI4115 is ideal for a variety of applications in water conditioning, environmental monitoring, and industrial processes.

The HI4115 silver/sulfide selective electrode is a complete potentiometric cell that contains a silver/silver chloride (Ag/AgCl) reference housed within a PEI plastic body with a potassium nitrate electrolyte. The internal elements are isolated from the sample by a compressed silver/silver sulfide sensing membrane.
Hanna’s solid-state combination ISEs are designed with a cone style junction. The skirted cone geometry of the sensor forms the liquid junction with the test solution at the tip of the junction cone, producing a highly stable reference potential and consistent flow rates of electrolyte into the solution. A simple press of the top portion of the ISE makes it easy to empty the electrolyte fill solution and replace when necessary.
Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI4115 silver/sulfide solid-state ISE can measure silver from 1µM (0.11 mg/L) to 1M (107,900 mg/L) and sulfide from 0.1µM (0.003 mg/L) to 1M (32,100 mg/L).
