The HI4113 is a liquid membrane, combination ion selective electrode (ISE) for the determination of nitrate (NO3–) in solution. The PVC membrane comprised with organic ion exchanger produces a potential change due to the nitrate ion exchange between the organic polymer membrane and the sample. The internal sensing elements are housed within a durable polyetherimide (PEI) body.
The HI4113 is ideal for a variety of applications in the food industry, agriculture, and water analysis.
The HI4113 nitrate ion selective electrode is a complete potentiometric cell that contains a silver/silver chloride (Ag/AgCl) reference housed within a PEI plastic body with an ammonium sulfate electrolyte. The internal elements are isolated from the sample by an organic polymer sensing membrane.
Hanna’s liquid membrane 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.
For the HI4113 to measure nitrate accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the nitrate ionic strength adjuster (ISA) solution. The ISA ensures that the activity coefficient is constant so the concentration of free nitrate ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI4113 nitrate liquid membrane ISE can measure from 10µM (0.62 mg/L) to 0.1M (6, 200 mg/L).

Replaceable Sensing Modules – Combination liquid membrane ISEs are electrodes that detect free ions in a solution. This type of ISE is designed to incorporate easy replacement of the sensing module.
Durable PEI Body – The probe body is composed of durable polyetherimide (PEI) plastic.
BNC Connection – The HI4113 has a universal BNC connector for easy connection to any benchtop meter with a female BNC probe input.
A liquid membrane ion selective electrode develops a voltage due to the ion exchange that occurs between the solution and the polymer membrane that contains organic ion exchange resin. When the ionic strength of the solution is fixed by the addition of ISA, the voltage is proportional to the concentration of free ions in solution.
