Sodium iodide standard solution for stray light testing according to Pharmacopeia

Sodium iodide standard solution is a reference reagent used to verify stray light performance in UV-Visible spectrophotometers according to pharmacopoeial standards in pharmaceutical and analytical laboratories.

🏭⚗️ Production
Solution is prepared by dissolving accurately weighed high-purity sodium iodide in appropriate solvent, usually water, to achieve the concentration required for stray light testing. It is dispensed into sealed vials to maintain stability, prevent contamination, and ensure reproducible optical properties.

🔬 Properties
Solution is clear, stable under recommended storage conditions, and provides high absorbance at specific wavelengths. These properties allow precise detection of stray light interference and verification of instrument linearity and precision at low transmittance levels.

🧪 Applications
In pharmaceutical and analytical laboratories, sodium iodide standard solution is used for calibration, verification, and performance qualification of spectrophotometers. It supports instrument qualification (IQ, OQ, PQ) and routine performance checks to ensure stray light does not affect analytical measurements, maintaining accuracy and compliance with regulatory standards.

⚠️ Safety
Solution should be handled using standard laboratory safety measures, including gloves and protective eyewear. It should be stored in a cool, dark place, and empty containers disposed of according to laboratory safety regulations.
