Hanna HI4014-00 Ionic Strength Adjuster (ISA)

Hanna HI4014-00 Ionic Strength Adjuster (ISA)

The Hanna HI4014-00 Ionic Strength Adjuster (ISA) is a 500 mL bottle of Ionic Strength Adjuster (ISA) specially formulated for use with potassium ion-selective electrodes (ISEs). This solution is essential for ensuring measurement accuracy by maintaining a consistent ionic strength in both standards and samples.

ISA solutions are a critical component in ISE measurements, as they suppress matrix effects, control pH, and enable concentration-based readings rather than activity-based ones.

Features

• Formulated for Potassium ISEs: Specifically designed for optimal performance with potassium ion-selective electrodes.

• Ensures Accurate Measurements: Maintains constant ionic strength across standards and samples to improve result precision.

• Ready to Use: No dilution required; simply add the appropriate amount to standards and test solutions before calibration and measurement.

• pH and Matrix Stabilization: In some cases, also helps regulate pH and minimize interferences from background ions.

Specifications

Usage Guidelines

• ISE Measurements: Always add a consistent amount of ISA to both calibration standards and samples when using a potassium ISE to ensure reproducible and accurate results.

• Volume Recommendation: Follow the ISE manufacturer’s guidelines for the exact volume of ISA to add, typically a fixed ratio to sample volume.

• Storage Instructions: Store at room temperature, tightly sealed, and away from direct sunlight.

Applications

The HI4014-00 ISA is ideal for use in:

• Water Quality Testing: Measuring potassium levels in potable, surface, or industrial water.

• Agricultural Analysis: Determining potassium concentrations in soil and fertilizers.

• Food & Beverage Industry: Monitoring potassium in processed foods and beverages.

• Environmental Monitoring: Supporting potassium ion analysis in environmental studies.
