Description

2,2',4,6,6'-Pentacb (Pcb-104) (13C12, 98%) 40+/-2 Ug/Ml In Nonane is a high-purity, isotopically labeled analytical standard essential for precise environmental and toxicological analysis. This product provides a critical reference for the accurate quantification and method validation of polychlorinated biphenyl (PCB) congeners in complex matrices. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions engaged in regulatory compliance monitoring, food safety testing, and advanced chemical research.

Application

• Internal Standard for GC-MS/GC-ECD Analysis: Used as a quantitative reference for the analysis of PCBs in environmental samples (soil, water, sediment).
• Method Development and Validation: Critical for establishing and verifying the accuracy, precision, and detection limits of analytical procedures for halogenated contaminants.
• Quality Assurance/Quality Control (QA/QC): Employed in spike/recovery experiments and as a system performance check to ensure data integrity in compliance-driven testing (e.g., EPA methods).
• Food and Feed Safety Testing: Enables precise measurement of PCB residues to ensure compliance with strict international food safety regulations.
• Biomedical and Toxicological Research: Supports studies on the environmental fate, bioaccumulation, and metabolic pathways of persistent organic pollutants (POPs).
• Calibration Standard: Used to create calibration curves for the accurate instrumental determination of PCB-104 and related congeners.

Quality Control

Every batch of our isotopically labeled standards is produced and verified under strict quality management protocols. The concentration is precisely confirmed against certified reference materials using high-resolution gas chromatography/mass spectrometry (GC-MS). We provide a comprehensive Certificate of Analysis (COA) with each unit, detailing the certified concentration, isotopic purity, chemical purity, and solvent verification to ensure traceability and reliability for your most demanding applications.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to the high volatility of the nonane solvent and the light-sensitive nature of the compound, ensure containers are kept sealed and upright in a well-ventilated area. For long-term stability, storage at -20°C is recommended.
