Description

2,3,3',4,4',5-Hexacb (Pcb-156) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, carbon-13 labeled analytical standard, essential for precise environmental and toxicological analysis. This certified reference material provides the critical isotopic purity and concentration accuracy required for reliable quantification and method validation in complex matrices. It is primarily used by analytical laboratories, research institutions, and regulatory bodies engaged in the detection and study of persistent organic pollutants.

Application

• Internal Standard for GC-MS/HRMS Analysis: Serves as a quantitative internal standard for the accurate measurement of native PCB-156 and other co-eluting congeners in environmental samples.
• Method Development and Validation: Used to establish and validate analytical procedures for polychlorinated biphenyls (PCBs) in compliance with EPA, EU, and other international standards.
• Quality Control/Quality Assurance (QC/QA): Employed in laboratory proficiency testing and as a spike for recovery studies to ensure data integrity and traceability.
• Food and Feed Safety Monitoring: Critical for the analysis of PCB residues in food chains, supporting safety regulations like EU maximum residue levels (MRLs).
• Environmental Forensics and Monitoring: Enables precise tracking and source apportionment of PCB contamination in soil, sediment, water, and biota.
• Toxicological and Metabolic Studies: Used in research to investigate the environmental fate, metabolic pathways, and toxicokinetics of dioxin-like PCBs.

Quality Control

Every batch of this analytical standard is manufactured and certified under strict quality management systems. The product undergoes comprehensive characterization using techniques including GC-MS, NMR, and HPLC to confirm identity, isotopic enrichment (99% 13C12), and precise concentration (40 ±2 µg/mL in nonane). A lot-specific Certificate of Analysis (COA) detailing all test results is supplied to ensure traceability and compliance with ISO Guide 34 and ISO/IEC 17025 principles.

Storage

Preserve in the original sealed vial as supplied, in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). For long-term stability, storage at -20°C is recommended. Allow the vial to equilibrate to room temperature before opening to prevent moisture condensation. Keep away from heat and ignition sources. The solution is provided in nonane; handle with appropriate ventilation and personal protective equipment.
