Description

2,2',3,4',5,6,6'-Heptacb (Pcb-188) (13C12, 99%) 40+/- 2 Ug/Ml In Nonane is a high-purity, isotopically labeled reference standard essential for advanced analytical chemistry. This compound provides a critical benchmark for the accurate quantification and identification of polychlorinated biphenyl (PCB) congeners in complex matrices. It is primarily required by environmental testing laboratories, regulatory agencies, and research institutions conducting trace-level analysis for compliance monitoring and toxicological studies. The solution is prepared in nonane to ensure stability and is characterized by its certified concentration and exceptional isotopic purity.

Application

• Primary Use: As an internal or calibration standard in Gas Chromatography-Mass Spectrometry (GC-MS) for the precise analysis of PCB-188 and related congeners.
• Environmental Monitoring: Quantifying PCB residues in soil, sediment, water, and air samples to assess contamination levels and ensure regulatory compliance (e.g., EPA methods).
• Food and Feed Safety: Testing for PCB contamination in agricultural products, seafood, and animal feed to uphold food safety standards.
• Forensic and Research Analysis: Supporting academic and industrial research into the environmental fate, bioaccumulation, and toxicology of persistent organic pollutants (POPs).
• Quality Assurance/Quality Control (QA/QC): Validating analytical methods, instrument performance, and laboratory proficiency in testing programs.
• Waste and Remediation Analysis: Characterizing PCB content in industrial waste, transformer oils, and materials from remediation sites.

Quality Control

Every batch of this isotopically labeled reference material is manufactured and verified under strict quality protocols to ensure traceability and accuracy for critical analytical applications. The concentration is certified against NIST-traceable standards, and the isotopic purity (99%) is confirmed by high-resolution mass spectrometry. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing the certified concentration, purity, method of analysis, and expiration date to support ISO/IEC 17025 accreditation and GLP compliance.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) to maintain solution integrity and minimize solvent evaporation due to the highly volatile nature of nonane. For long-term stability, storage at -20°C is recommended. Allow the vial to equilibrate to room temperature before opening to prevent moisture condensation.
