Description

The HI4013 is a liquid membrane, half-cell 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 epoxy body. The HI4013 is ideal for a variety of applications in the food industry, agriculture, and water analysis. Liquid membrane sensor Detection from 0.62 to 6,200 mg/L NO3- For use with HI5315 reference half-cell The HI4013 nitrate ion selective electrode is a potentiometric half-cell sensor housed within an epoxy body. The internal elements are isolated from the sample by an organic polymer sensing membrane. This liquid membrane sensor requires a separate reference electrode to complete the measurement system. Hanna’s liquid membrane 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 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 HI4013 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.
