Description

Anion Standard - Propionate is a high-purity analytical reference material, essential for precise calibration and quality control in modern laboratories. This standard provides the definitive benchmark for the accurate quantification of propionate ions in complex sample matrices. It is a critical tool for analytical chemists and quality assurance professionals in the pharmaceutical, food & beverage, and environmental monitoring industries.

Application

• Analytical Method Development & Validation: Primary standard for establishing and validating chromatographic (e.g., Ion Chromatography) and spectroscopic methods for anion analysis.
• Pharmaceutical Quality Control: Used in the assay and impurity profiling of drug substances and finished products where propionate is a counter-ion or degradation product.
• Food & Beverage Analysis: Calibration standard for monitoring propionate levels as a preservative (E280) in baked goods, dairy products, and animal feed.
• Environmental & Water Testing: Essential for quantifying short-chain fatty acids like propionate in wastewater, fermentation broths, and environmental samples.
• Clinical & Diagnostic Testing: Reference material for in-vitro diagnostic kits and assays measuring propionate in biological fluids for metabolic studies.
• Industrial Process Control: Serves as a calibration standard for monitoring propionate concentrations in chemical manufacturing and biotechnology processes.

Quality Control

Our Anion Standard - Propionate is manufactured under strict quality management systems. Each batch is subjected to rigorous identity, purity, and homogeneity testing using validated analytical methods, including Ion Chromatography (IC) and Titration. A comprehensive Certificate of Analysis (COA) detailing exact purity, trace metal content, and anion/cation impurities is provided with every unit to ensure traceability and reliability for your critical analyses.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed immediately after use to prevent absorption of atmospheric moisture, which can affect concentration and stability.
