Description

2,2',4,4',6,6'-Hexacb (Pcb-155) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, isotopically labeled reference standard essential for analytical quantification and method validation. This product provides a critical tool for ensuring accuracy and traceability in environmental and food safety testing, where precision is non-negotiable. It is primarily required by analytical laboratories, regulatory bodies, and research institutions involved in the detection and monitoring of persistent organic pollutants.

Application

• Quantitative Analytical Reference Standard: Used as a primary standard for the calibration of GC-MS, LC-MS, and other chromatographic systems in the analysis of PCB congeners.
• Method Development and Validation: Serves as a spiking agent to establish recovery rates, detection limits, and the accuracy of analytical procedures for PCBs.
• Quality Assurance/Quality Control (QA/QC): Employed in internal and external quality control programs to verify the performance of testing laboratories and ensure data integrity.
• Environmental Monitoring: Critical for the accurate quantification of PCB-155 in soil, sediment, water, and air samples to assess contamination levels and compliance with environmental regulations.
• Food and Feed Safety Analysis: Used to detect and quantify PCB residues in food products, animal feed, and edible oils to enforce safety standards.
• Certified Reference Material (CRM) Production: Acts as a key component in the preparation of certified reference materials for proficiency testing and laboratory accreditation.
• Toxicological and Metabolic Studies: The carbon-13 labeled (13C12) structure allows for precise tracking in studies investigating the environmental fate, bioaccumulation, and metabolic pathways of PCBs.
