Description

Aroclor 1254, 1X1Ml, Iso, 1000Ug/Ml is a high-purity, isooctane-based analytical standard solution containing the polychlorinated biphenyl (PCB) congener Aroclor 1254 at a certified concentration of 1000 µg/mL. This product is essential for precise calibration, method validation, and quality control in environmental and analytical laboratories, ensuring accurate quantification of PCB contaminants. It is primarily needed by environmental testing facilities, research institutions, and industrial quality control labs engaged in the analysis of persistent organic pollutants (POPs) in soil, water, and biological samples.

Application

• Environmental Analysis: Calibration standard for GC-MS/ECD analysis of PCBs in water, wastewater, soil, and sediment as per EPA methods (e.g., EPA 8082).
• Food Safety Testing: Reference material for monitoring PCB contamination in food products, fats, and oils to ensure regulatory compliance.
• Industrial Hygiene: Analytical standard for assessing occupational exposure and monitoring PCBs in workplace air and wipe samples.
• Research & Development: Critical reagent for studying the environmental fate, toxicology, and remediation techniques for PCBs.
• Waste Characterization: Used in the analysis of industrial waste and transformer oils to determine PCB content for proper disposal classification.
• Method Validation: Serves as a primary standard for developing, validating, and verifying analytical methods for chlorinated hydrocarbons.
• Quality Assurance/Quality Control (QA/QC): Used as a spike or control standard in laboratory proficiency testing and internal QC programs.
• Regulatory Compliance: Essential for testing to comply with global regulations such as the Stockholm Convention on POPs, EU directives, and TSCA.

Quality Control

This analytical standard is manufactured and certified under strict quality control protocols to ensure traceability, accuracy, and consistency. Each batch is analyzed using validated methods, including GC-MS and/or GC-ECD, against certified reference materials. A comprehensive Certificate of Analysis (COA) is provided, detailing the certified concentration, uncertainty, purity, solvent verification, and analytical method used. Our quality system is designed to support ISO/IEC 17025 and GLP compliant laboratories.

Storage

Preserve in the supplied, tightly closed amber vial or septum-sealed ampule. Store at 2-8°C (refrigerated). This product is light-sensitive (store away from light) and the solvent is highly volatile and flammable. Keep away from heat, sparks, and open flame. For long-term stability, store under recommended refrigeration conditions and allow to equilibrate to room temperature before use.
