Cadmium Half-Cell Ion Selective Electrode (ISE) HI4003
CA$1,073.00
SKU
4003
The HI4003 is a solid state, half-cell ion selective electrode (ISE) for the determination of cadmium (Cd2+) in solution. The mixed cadmium sulfide/silver sulfide sensing pellet produces a potential change due to the cadmium ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable epoxy body. The HI4003 is ideal for a variety of applications in electroplating, battery construction, and in the laboratory.

The HI4003 cadmium ion-selective electrode is a potentiometric half-cell sensor housed within an epoxy body. The internal elements are isolated from the sample by a compressed cadmium sulfide/silver sulfide sensing membrane. This solid-state sensor requires a separate reference electrode to complete the measurement system.
Hanna’s solid-state half-cell ISEs are designed for use with the HI5315 reference half-cell. The reference half-cell features a cone style junction. The skirted cone geometry of the reference 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.
For the HI4003 to measure cadmium accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the HI4000-00 ionic strength adjuster (ISA) solution. The ISA ensures that the activity coefficient is constant so the concentration of free cadmium ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI4003 cadmium solid-state ISE can measure from 0.1µM (0.01 mg/L) to 0.1M (11,200 mg/L).
