Description

1,2,3,4,7,8,9-Heptachlorodibenzofuran (13C12, 99%) 50 Ug/Ml In Nonane is a high-purity, isotopically labeled analytical standard essential for precise quantitative analysis and method validation. This certified reference material provides the critical accuracy and traceability required for compliance testing in environmental and food safety monitoring. It is primarily used by analytical laboratories and research institutions specializing in the detection of persistent organic pollutants (POPs) like dioxins and furans.

Application

• Internal Standard for GC-MS/MS Analysis: Used as a quantitative internal standard in the analysis of polychlorinated dibenzofurans (PCDFs) to ensure method accuracy and correct for instrument variability.
• Environmental Monitoring and Compliance: Critical for testing soil, sediment, water, and air samples to comply with international regulations such as the Stockholm Convention on POPs.
• Food and Feed Safety Analysis: Employed in the quantification of dioxin-like compounds in foodstuffs, animal feed, and edible oils to meet EU and FDA regulatory limits.
• Method Development and Validation: Serves as a key component in developing, calibrating, and validating analytical methods for congener-specific dioxin analysis.
• Quality Control/Quality Assurance (QC/QA): Used in proficiency testing and inter-laboratory comparisons to ensure consistent and reliable analytical results across testing facilities.
• Toxicological and Environmental Fate Studies: Supports research into the environmental persistence, bioaccumulation, and toxicological impact of chlorinated dibenzofurans.
• Waste and Incineration Byproduct Analysis: Essential for monitoring emissions and residues from industrial processes and waste incineration plants.

Quality Control

Every batch of this analytical standard is manufactured and certified under strict quality management protocols. The product undergoes comprehensive analysis using state-of-the-art techniques including GC-MS and HPLC to verify identity, isotopic enrichment, and chemical purity. A detailed Certificate of Analysis (COA) is provided, which includes batch-specific data on concentration, solvent, uncertainty, and traceability to national or international standards. Our quality system is designed to support compliance with ISO 17034 and ISO/IEC 17025 requirements for reference material producers.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). The solution is provided in nonane, which is flammable; keep away from heat, sparks, and open flame. For long-term stability, store in a dedicated freezer at or below -20°C. Allow the vial to reach room temperature before opening to prevent moisture condensation.
