Description

1,2,3,7,8-Pentachlorodibenzo-p-Dioxin (13C12, 99%) 50 Ug/Ml In Nonane is a high-purity, isotopically labeled analytical standard essential for precise environmental and toxicological analysis. This certified reference material provides the accuracy and traceability required for regulatory compliance and advanced research. It is primarily used by analytical laboratories, environmental testing facilities, and research institutions engaged in dioxin monitoring, method validation, and mass spectrometry-based quantification.

Application

• Internal Standard for GC-MS/MS Analysis: Critical for the accurate quantification of native polychlorinated dibenzo-p-dioxins (PCDDs) in complex matrices.
• Method Development and Validation: Used to establish and verify analytical procedures according to EPA, EU, and other international standards.
• Environmental Monitoring: Essential for testing soil, water, sediment, and air samples for dioxin contamination from industrial processes or waste incineration.
• Food and Feed Safety Analysis: Employed in the detection and quantification of dioxin levels to ensure compliance with strict food safety regulations (e.g., EU Commission Regulations).
• Toxicological and Biomedical Research: Serves as a key reagent in studies investigating the bioaccumulation, metabolism, and health impacts of dioxin congeners.
• Quality Control and Proficiency Testing: Used by reference material producers and testing laboratories to ensure the accuracy and reliability of analytical results.
• Forensic Analysis: Aids in source identification and apportionment in environmental forensic investigations involving dioxin contamination.

Quality Control

This certified reference material is produced under strict quality management protocols. Each batch is characterized using advanced analytical techniques including High-Resolution Gas Chromatography/Mass Spectrometry (HRGC/HRMS) to confirm isotopic purity (99% 13C12), chemical purity, and solution concentration accuracy. A comprehensive Certificate of Analysis (COA) is supplied, providing traceability to NIST-traceable standards where applicable. Our quality system is designed to support compliance with ISO/IEC 17025 and ISO Guide 34 requirements for reference material producers.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to the highly volatile nature of the nonane solvent and the light-sensitive properties of the analyte, the vial must be kept sealed and allowed to equilibrate to room temperature before opening to prevent condensation. For long-term stability, storage at -20°C is recommended.
