Description

2,5-Dicb (Pcb-9) (13C12, 98-99%) 40+/-2 Ug/Ml In Nonane is a high-purity, isotopically labeled analytical standard, specifically formulated as a solution in nonane. This product is essential for ensuring the accuracy and reliability of quantitative analysis in complex environmental and biological matrices, providing a critical reference point for method validation and calibration. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions engaged in the trace-level detection and quantification of polychlorinated biphenyl (PCB) congeners.

Application

• Internal Standard for GC-MS/MS Analysis: Serves as a crucial quantitative reference for the precise measurement of specific PCB congeners in environmental samples.
• Method Development and Validation: Used to establish and verify the accuracy, precision, and detection limits of analytical protocols for PCB detection.
• Quality Control/Quality Assurance (QC/QA): Integral for laboratory proficiency testing, instrument calibration, and ensuring data integrity in compliance-driven testing.
• Environmental Monitoring: Enables the trace analysis of PCBs in soil, water, sediment, and air samples to assess contamination and regulatory compliance.
• Food and Feed Safety Testing: Applied in the analysis of PCB residues to ensure products meet international safety standards (e.g., EU, FDA).
• Biomedical and Toxicological Research: Used in studies investigating the bioaccumulation, metabolism, and health impacts of PCBs.
• Forensic Analysis: Supports the identification and sourcing of PCB contaminants in legal and environmental forensic investigations.

Quality Control

Every batch of our 2,5-Dicb (Pcb-9) (13C12) solution is manufactured and verified under strict quality protocols to ensure identity, purity, and concentration accuracy. The product is characterized using advanced techniques including GC-MS and NMR to confirm isotopic enrichment and chemical purity. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing batch-specific results for concentration, isotopic purity, and solvent verification. Our quality system supports compliance with relevant standards for analytical reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). The solution is provided in a strong acid/organic solvent (nonane); handle with appropriate precautions in a well-ventilated area. For long-term stability, avoid repeated freeze-thaw cycles and keep the vial tightly sealed to prevent solvent evaporation and concentration change.
