Hanna HI4012-00 Ionic Strength Adjuster

Hanna HI4012-00 Ionic Strength Adjuster

The HI4012-00 Ionic Strength Adjuster (ISA) by Hanna Instruments is a specially formulated solution used to maintain constant ionic strength in both sample and standard solutions during ion-selective electrode (ISE) measurements. By controlling ionic strength, the ISA allows for accurate concentration-based readings rather than activity-based measurements, ensuring improved precision and consistency.

Features

• Maintains Constant Ionic Strength: Minimizes variability between samples and calibration standards for more reliable ISE measurements.

• Improves Accuracy: Enables accurate concentration determinations by reducing the influence of fluctuating ionic activity.

• Reduces Matrix Effects: Helps eliminate sample interferences and adjusts pH where applicable.

• Universal Use: Compatible with various types of ion-selective electrodes (ISEs), including those for fluoride, iodide, and nitrate.

• High Purity and Stability: Prepared with reagent-grade chemicals for consistent performance in laboratory and field applications.

Specifications

Application Guidelines

• ISA must be added to both the calibration standards and the sample solutions before taking ISE measurements.

• Typical usage involves adding a fixed volume (e.g., 2 mL ISA per 100 mL sample) to standardize ionic strength across all solutions.

• In some ISE applications, the ISA also adjusts the pH to the optimal range for electrode performance.

Applications

The HI4012-00 Ionic Strength Adjuster is essential for:

• Environmental Testing: Ensures accurate readings of ions in water and soil samples.

• Food & Beverage Analysis: Used when measuring fluoride or nitrate in consumable products.

• Pharmaceutical & Chemical Labs: Supports precision in compound analysis and quality control.

• Research & Education: Enhances consistency and reliability in academic experiments and studies.
