Description

1,2,3,7,8,9-Hexachlorodibenzofuran (13C12, 99%) 50 Ug/Ml In Nonane is a high-purity, isotopically labeled analytical standard, essential for precise quantitative analysis and method validation in environmental and toxicological testing. This certified reference material provides a critical benchmark for the accurate detection and quantification of polychlorinated dibenzofurans (PCDFs), a class of persistent organic pollutants. It is primarily required by analytical laboratories, regulatory bodies, and research institutions engaged in dioxin analysis, food safety monitoring, and environmental compliance testing to ensure data integrity and meet stringent international standards.

Application

• Quantitative Analytical Standard for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Internal Standard in isotope dilution methods for the precise determination of native 1,2,3,7,8,9-Hexachlorodibenzofuran in complex matrices.
• Method Development and Validation for testing protocols according to US EPA, EU, and other international regulations.
• Quality Control/Quality Assurance (QC/QA) in commercial and regulatory laboratories analyzing environmental samples (soil, water, air emissions).
• Food and Feed Safety Testing for monitoring PCDF contamination levels to comply with EU and global maximum residue limits (MRLs).
• Toxicological and Biomedical Research studying the environmental fate, bioaccumulation, and health effects of dioxin-like compounds.
• Proficiency Testing and inter-laboratory comparison schemes to ensure analytical competency and data comparability.
