Description

2,3,3',4,4',5,5',6-Octacb (Pcb-205) (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 isotopically enriched compound provides an invaluable internal reference for the accurate quantification of polychlorinated biphenyl (PCB) congeners via mass spectrometry. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions engaged in regulatory compliance monitoring, food safety analysis, and advanced chemical fate studies.

Application

• Internal Standard for GC-MS/LC-MS Analysis: Used as a quantitative reference for the analysis of PCBs in complex matrices.
• Environmental Monitoring: Critical for testing soil, sediment, water, and air samples for PCB contamination to meet EPA and global regulatory standards.
• Food and Feed Safety Testing: Employed in the accurate detection and quantification of PCB residues in food products, animal feed, and edible oils.
• Toxicology and Metabolic Studies: Serves as a stable-isotope tracer in research investigating the environmental fate, bioaccumulation, and metabolic pathways of PCBs.
• Quality Control and Method Validation: Essential for developing, validating, and ensuring the accuracy and precision of analytical methods in accredited laboratories.
• Waste and Industrial Effluent Analysis: Used to monitor PCB levels in industrial waste streams and remediation projects.

Quality Control

Every batch of our 13C12-labeled PCB-205 standard is manufactured and verified under strict quality protocols to ensure the highest isotopic and chemical purity for trace-level analysis. We provide a comprehensive Certificate of Analysis (COA) with each unit, detailing the concentration, isotopic enrichment, solvent verification, and chromatographic purity. Our quality system supports compliance with standards relevant to analytical reference materials, ensuring reliability for your most demanding applications.

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, ensure containers are securely sealed and stored upright in a well-ventilated area. For long-term stability, storage at -20°C is recommended.
