Description

Polychlorinated Biphenyl (Kanechlor 300) is a specific, standardized mixture of chlorinated biphenyl congeners, historically significant as a dielectric fluid and industrial chemical. Its consistent composition is critical for research, analytical standard preparation, and specialized industrial applications where a defined PCB profile is required. This product is primarily utilized by environmental testing laboratories, regulatory agencies, and chemical manufacturers engaged in method development, calibration, and legacy system analysis.

Application

• Analytical Reference Standard: Serves as a certified reference material (CRM) for the calibration of gas chromatography (GC) and mass spectrometry (MS) instruments in environmental testing.
• Environmental Research: Used in fate and transport studies, toxicological research, and the development of remediation technologies for PCB-contaminated sites.
• Method Development & Validation: Essential for laboratories establishing or verifying analytical procedures for PCB detection and quantification in various matrices (soil, water, tissue).
• Quality Control/Quality Assurance (QC/QA): Employed as a spike or control sample to ensure the accuracy and precision of analytical data in compliance monitoring programs.
• Educational & Forensic Analysis: Used in academic settings for teaching advanced analytical chemistry and in forensic investigations to identify PCB sources.
• Specialized Industrial Research: Applied in closed-system studies for material compatibility, transformer fluid analysis, and the development of PCB-free alternatives.

Quality Control

Every batch of Polychlorinated Biphenyl (Kanechlor 300) is characterized using advanced chromatographic techniques to ensure congener profile consistency and purity. Our quality system is designed to meet the stringent requirements of analytical reference material production. A comprehensive Certificate of Analysis (COA) detailing the congener-specific composition, assay, and analytical methods (GC/GC-MS) is provided with each shipment to support your traceability and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area, preferably at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to the persistent nature of PCBs, ensure storage is in compliance with all local and international environmental regulations for controlled substances.
