Description

2,2',6-Tricb (Pcb-19) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, stable-isotope labeled standard of a polychlorinated biphenyl congener, provided as a certified reference material in a nonane solution. This product is essential for ensuring the accuracy, traceability, and regulatory compliance of analytical methods in environmental and food safety testing. It is primarily required by analytical laboratories, contract research organizations (CROs), and quality control departments involved in the precise quantification of PCB contaminants.

Application

• Internal Standard for GC-MS/GC-ECD Analysis: Used as a quantitative internal standard for the accurate measurement of PCB-19 and related congeners in complex matrices.
• Environmental Monitoring: Critical for calibrating instruments and validating methods in the analysis of soil, sediment, water, and air samples for persistent organic pollutants (POPs).
• Food and Feed Safety Testing: Enables reliable detection and quantification of PCB residues in food products, animal feed, and edible oils to comply with global safety regulations.
• Method Development and Validation: Serves as a key component in developing, optimizing, and accrediting (e.g., ISO 17025) analytical procedures for halogenated contaminants.
• Quality Assurance/Quality Control (QA/QC): Used in proficiency testing, inter-laboratory comparisons, and as a system suitability check to ensure ongoing analytical performance.
• Clinical and Toxicological Research: Supports studies investigating the bioaccumulation, metabolism, and health impacts of polychlorinated biphenyls.

Quality Control

Every batch of this certified reference material is produced and analyzed under strict quality management protocols. The 99% isotopic purity (13C12) and precise concentration (40 ± 2 µg/mL in nonane) are guaranteed through rigorous characterization using techniques such as GC-MS and NMR. A comprehensive Certificate of Analysis (COA) is supplied with each unit, providing batch-specific data on identity, purity, concentration, and uncertainty traceable to national standards. Our quality system supports compliance with ISO Guide 34 and ISO/IEC 17025 requirements.

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 adequate ventilation and keep away from heat and ignition sources. For long-term stability, storage at -20°C is recommended.
