Description

4,4'-Dicb (Pcb-15) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, isotopically labeled reference standard of the polychlorinated biphenyl (PCB) congener PCB-15, where all carbon atoms are the stable isotope Carbon-13. This product is essential for ensuring the accuracy and reliability of analytical methods, providing a critical tool for precise quantification and method validation. It is primarily required by environmental testing laboratories, regulatory agencies, and research institutions engaged in trace-level analysis of persistent organic pollutants (POPs) for compliance monitoring and scientific studies.

Application

• Internal Standard for GC-MS/MS Analysis: Used as a quantitative reference for the accurate measurement of PCB-15 and related congeners in complex matrices.
• Method Development and Validation: Critical for establishing and verifying the precision, accuracy, and detection limits of analytical procedures for PCBs.
• Quality Assurance/Quality Control (QA/QC): Serves as a spike or recovery standard to monitor the performance and consistency of analytical runs in accredited laboratories.
• Environmental Monitoring: Enables the precise tracking of PCB contamination in soil, sediment, water, and air samples to meet regulatory standards like EPA methods.
• Food and Feed Safety Testing: Employed in the analysis of PCB residues to ensure compliance with maximum residue limits (MRLs) in the food supply chain.
• Calibration Standard: Used to prepare calibration curves for the instrumental quantification of PCBs, ensuring traceability to a known reference material.
• Research on PCB Fate and Transport: Supports isotopic tracer studies investigating the environmental behavior, degradation, and bioaccumulation of PCBs.

Quality Control

Every batch of this isotopically labeled reference material is produced and verified under stringent quality protocols to ensure identity, purity, and concentration accuracy. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, providing batch-specific data for isotopic enrichment, chemical purity, and solution concentration.

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, it is recommended to store at -20°C.
