Description

2',3,4,4',5-Pentacb (Pcb-123) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, isotopically labeled standard solution, essential for precise analytical quantification and method validation. This product provides a critical reference for ensuring accuracy and traceability in sensitive environmental and food safety testing protocols. It is primarily required by analytical laboratories, regulatory bodies, and research institutions engaged in the detection and monitoring of polychlorinated biphenyl (PCB) congeners.

Application

• Internal Standard for GC-MS/GC-ECD Analysis: Used as a quantitative reference for the analysis of PCB-123 and related congeners in complex matrices.
• Environmental Monitoring: Calibration and quality control for testing PCBs in soil, sediment, water, and air samples to comply with environmental regulations.
• Food and Feed Safety Testing: Accurate quantification of PCB residues in food products, animal feed, and edible oils to ensure consumer safety.
• Method Development and Validation: Serves as a certified reference material for establishing and validating analytical methods according to ISO, EPA, and other international standards.
• Forensic and Diagnostic Analysis: Provides a traceable standard for investigating contamination sources and conducting diagnostic studies on PCB exposure.
• Clinical and Biomedical Research: Used in studies investigating the toxicokinetics, metabolism, and biological impact of specific PCB congeners.

Quality Control

Every batch of this isotopically labeled standard is manufactured and certified to meet the highest standards of purity and concentration accuracy. Quality is assured through rigorous analysis via High-Resolution Gas Chromatography/Mass Spectrometry (HRGC/HRMS) and other orthogonal techniques. A comprehensive Certificate of Analysis (COA) is supplied with each unit, detailing the certified concentration, isotopic enrichment, purity, and uncertainty traceable to NIST or other international standards.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). The solution is provided in nonane, which is highly volatile and flammable; ensure proper ventilation and adhere to standard laboratory safety practices for organic solvents.
