Description

1,2,3,7,8-Pentachlorodibenzofuran (13C12, 99%) 50 Ug/Ml In Nonane is a high-purity, isotopically labeled analytical standard essential for precise quantitative analysis. This certified reference material provides the critical internal standard needed for accurate calibration and recovery studies in complex matrices. It is primarily used by analytical laboratories and research institutions engaged in environmental monitoring and food safety testing. The product is supplied as a ready-to-use solution in nonane for convenience and stability.

Application

• Internal Standard for Dioxin/Furan Analysis: Critical for isotope dilution high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) in EPA Methods 1613, 8290, and similar protocols.
• Environmental Monitoring: Quantification of polychlorinated dibenzofurans (PCDFs) in soil, sediment, water, and air particulate samples to assess contamination levels.
• Food and Feed Safety Testing: Accurate determination of toxic congeners in compliance with EU and global regulations for dioxins and PCBs in foodstuffs, including fish, meat, and dairy products.
• Waste and Emission Analysis: Monitoring of industrial incinerator outputs and other thermal processes for regulatory compliance and environmental impact assessments.
• Clinical and Toxicological Research: Used in studies investigating the bioaccumulation, metabolism, and health effects of persistent organic pollutants (POPs).
• Quality Assurance/Quality Control (QA/QC): Serves as a spike for method validation, recovery checks, and proficiency testing programs in accredited laboratories.

Quality Control

This analytical standard is manufactured and certified under strict quality control protocols to ensure the highest level of accuracy and traceability required for compliance testing. Each batch is confirmed for isotopic purity (99% 13C12) and chemical purity (99%) using advanced techniques like HRGC/HRMS and NMR. A comprehensive Certificate of Analysis (COA) is supplied, detailing the exact concentration, uncertainty, method of analysis, and traceability to international standards.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) upon receipt. Due to the highly volatile nature of the nonane solvent, ensure containers are kept upright in a well-ventilated area and allowed to equilibrate to room temperature before opening to prevent condensation. For long-term stability, storage at -20°C is recommended.
