Description

Calcium Ion Chromatography Standard is a high-purity reference material essential for accurate quantitative analysis in ion chromatography (IC) systems. It serves as a critical calibration standard for ensuring measurement precision and method validation in quality control and research laboratories. This standard is indispensable for analytical chemists and quality assurance professionals in industries such as pharmaceuticals, environmental monitoring, food & beverage, and power generation.

Application

• Primary Calibration Standard for quantifying calcium ion (Ca²⁺) concentrations in ion chromatography (IC) systems.
• Method Development and Validation for new analytical procedures in compliance with regulatory guidelines (e.g., USP, EP, ASTM).
• Quality Control Testing of pharmaceuticals, nutraceuticals, and injectables where calcium content is a critical specification.
• Environmental Analysis of water quality, including drinking water, wastewater, and soil leachates for hardness and mineral content.
• Food and Beverage Analysis for monitoring calcium fortification levels and nutritional labeling in products like dairy, juices, and infant formula.
• Power Industry Monitoring for analyzing calcium and other cations in boiler feed water, steam condensate, and cooling water to prevent scaling.
• Clinical and Biomedical Research for the analysis of physiological fluids and cell culture media.
• Instrument Performance Verification to check the accuracy, linearity, and detection limits of IC equipment.

Quality Control

Our Calcium Ion Chromatography Standard is manufactured and tested under strict quality management systems. Each batch is certified against NIST-traceable reference materials to ensure the highest accuracy and lot-to-lot consistency required for reliable calibration. A comprehensive Certificate of Analysis (COA) is provided, detailing the exact concentration, uncertainty, purity, and test methods (e.g., gravimetric, titrimetric, ICP-OES). We support compliance with GMP, ISO/IEC 17025, and relevant pharmacopeial guidelines.

Storage

Preserve in the original tightly closed container, protected from light. Store at controlled room temperature (15-25°C). Do not freeze. For maximum stability, the solution should be kept in an inert environment if specified. Always handle with appropriate laboratory practices to avoid contamination.
