Description

2,3,3',5,5'-Pentacb (Pcb-111) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, isotopically labeled standard of a specific polychlorinated biphenyl (PCB) congener, essential for precise analytical quantification and method validation. This product provides a critical reference point for laboratories requiring the highest level of accuracy in trace-level environmental and biological analysis. It is primarily used by analytical chemists and researchers in environmental testing, food safety, and regulatory compliance sectors for calibration and quality assurance in GC-MS and LC-MS workflows.

Application

• Quantitative Analytical Standard: Primary use as a certified reference material (CRM) for the calibration of gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) systems in trace analysis.
• Environmental Monitoring: Critical for the accurate detection and quantification of PCB-111 in soil, sediment, water, and air samples to assess contamination levels and comply with environmental regulations (e.g., EPA methods).
• Food and Feed Safety Analysis: Used in laboratories to test for PCB residues in food products, animal feed, and edible oils, ensuring compliance with global safety standards like EU maximum residue levels (MRLs).
• Method Development and Validation: Serves as a spike-in standard for recovery studies and for validating new analytical methods for PCB congener-specific analysis, ensuring method accuracy and precision.
• Clinical and Toxicological Research: Employed in biomonitoring studies to measure PCB exposure levels in human serum, adipose tissue, or other biological matrices.
• Quality Control/Quality Assurance (QC/QA): Integral part of laboratory QC protocols, used as an internal standard to correct for instrument variability and matrix effects during sample analysis.

Quality Control

Every batch of our isotopically labeled PCB-111 standard is manufactured and certified to the highest standards of purity and concentration accuracy. The product undergoes rigorous analysis using advanced techniques including GC-MS and NMR to confirm isotopic enrichment, chemical purity, and solution concentration. A comprehensive Certificate of Analysis (COA) is supplied with each unit, detailing the certified concentration, purity, expiration date, and uncertainty measurements. Our quality system is designed to support ISO/IEC 17025 and ISO 17034 accredited laboratories.

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 and the light-sensitive properties of the analyte, the vial must be kept sealed when not in use and allowed to equilibrate to room temperature before opening to prevent condensation.
