Description

3,3',4,4',5-Pentacb (Pcb-126) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, stable-isotope labeled analytical standard essential for precise environmental and toxicological research. This product provides a critical reference material for the accurate quantification and monitoring of dioxin-like polychlorinated biphenyls (PCBs), which are persistent organic pollutants of significant regulatory concern. It is primarily used by analytical laboratories, environmental testing facilities, and research institutions requiring certified reference materials for method validation, calibration, and quality control in gas chromatography-mass spectrometry (GC-MS) analysis.

Application

• Internal Standard for GC-MS/MS Analysis: Serves as a quantitative internal standard for the precise determination of PCB-126 and other co-planar PCBs in complex matrices.
• Environmental Monitoring and Compliance Testing: Used in the analysis of soil, sediment, water, and air samples to assess contamination levels and ensure regulatory compliance (e.g., EPA, EU directives).
• Food and Feed Safety Analysis: Critical for testing dioxin and PCB levels in foodstuffs, animal feed, and edible oils to meet global food safety standards.
• Toxicological and Biomedical Research: Enables studies on the bioaccumulation, metabolic pathways, and health effects of dioxin-like compounds.
• Method Development and Validation: Provides a certified reference material for developing, optimizing, and validating analytical methods in accredited laboratories.
• Quality Assurance/Quality Control (QA/QC): Used in proficiency testing and inter-laboratory comparisons to ensure accuracy and reproducibility of analytical results.
• Waste and Industrial Effluent Analysis: Applied in characterizing industrial discharges and monitoring waste treatment processes for persistent organic pollutants.

Quality Control

This certified reference material is produced and verified under strict quality management protocols. Each batch is characterized for identity, purity, and concentration using advanced analytical techniques including high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS) and nuclear magnetic resonance (NMR). The solution concentration is precisely quantified against a primary standard. A comprehensive Certificate of Analysis (COA) is supplied with each unit, detailing the certified value, measurement uncertainty, and traceability to national or international standards, ensuring compliance with ISO Guide 34 and ISO/IEC 17025 requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) or as indicated on the label/COA. Due to the highly volatile nature of the nonane solvent and the light-sensitive properties of the analyte, the vial must be kept sealed when not in use and stored upright in a dedicated, well-ventilated refrigerator. Allow the solution to reach room temperature before opening to prevent condensation.
