Description

2,2',6,6'-Tetracb (Pcb-54) (13C12, 98%) 40+/-2 Ug/Ml In Nonane is a high-purity, isotopically labeled analytical standard, specifically formulated as a solution in nonane for precise quantitative analysis. This product is essential for laboratories requiring the highest level of accuracy and traceability in their environmental and toxicological testing protocols. It is primarily used by analytical chemists and researchers in environmental monitoring, food safety, and regulatory compliance sectors for the calibration and validation of sophisticated detection equipment like GC-MS and LC-MS.

Application

• Internal Standard for Mass Spectrometry: Serves as a critical quantitative reference in isotope dilution methods for the analysis of polychlorinated biphenyls (PCBs) and related persistent organic pollutants (POPs).
• Environmental Analysis: Calibration and quality control for testing soil, sediment, water, and air samples to monitor PCB contamination levels and comply with environmental regulations (e.g., EPA methods).
• Food and Feed Safety Testing: Used in the accurate quantification of PCB residues in food products, animal feed, and edible oils to ensure compliance with international safety standards.
• Clinical and Toxicological Research: Enables precise measurement of PCB metabolites or exposure markers in biological matrices such as blood, serum, and tissue samples.
• Method Development and Validation: A key reagent for developing, optimizing, and validating new analytical methods for halogenated aromatic compounds.
• Proficiency Testing and Laboratory Accreditation: Provides a traceable standard for inter-laboratory comparison studies and for meeting ISO/IEC 17025 accreditation requirements.

Quality Control

Every batch of this analytical standard is manufactured and verified under strict quality-controlled conditions to ensure identity, purity, and concentration accuracy. The product is characterized using advanced techniques including GC-MS, HPLC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing the exact concentration, isotopic enrichment, purity, and solvent verification. Our quality system is designed to support GLP/GMP compliance and traceability requirements for regulatory testing.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to its highly volatile nature, ensure the container is securely sealed and stored upright to prevent leakage or solvent evaporation. Keep away from heat and open flames.
