Description

2,2′,3,3′,5‐Pentabromodiphenyl Ether Standard Solution is a high-purity analytical reference material essential for precise quantification and method validation. This certified solution is critical for ensuring data integrity in environmental monitoring and regulatory compliance testing. It is primarily utilized by analytical laboratories, quality control facilities, and research institutions involved in the analysis of brominated flame retardants and persistent organic pollutants.

Application

• Analytical Reference Standard for the calibration of GC-MS, GC-ECD, and LC-MS systems.
• Method Development and Validation for the detection of polybrominated diphenyl ethers (PBDEs) in various matrices.
• Quality Control (QC) and Quality Assurance (QA) in environmental testing laboratories.
• Research and Development of analytical techniques for persistent organic pollutants (POPs) under the Stockholm Convention.
• Certified Material for proficiency testing and inter-laboratory comparison studies.
• Regulatory Compliance Testing for consumer products, electronics, and environmental samples (e.g., soil, water, biota).

Quality Control

Our standard solutions are manufactured and certified under strict quality management systems. Each batch is precisely prepared using high-purity solvents and characterized via multiple orthogonal analytical techniques to ensure exact concentration and identity. A comprehensive Certificate of Analysis (COA) is supplied with each unit, detailing the certified value, uncertainty, method of analysis, and traceability to primary standards. Our quality protocols are designed to meet the rigorous demands of ISO/IEC 17025 accredited laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store at the recommended temperature specified on the certificate of analysis, typically between 2°C and 8°C for long-term stability. Allow the solution to equilibrate to room temperature before use and invert gently to ensure homogeneity. Do not freeze.
