Description

Aroclor 1248, 1X1Ml, Iso, 1Ug/Ml is a standardized analytical reference material, specifically a 1 µg/mL solution of the polychlorinated biphenyl (PCB) mixture Aroclor 1248 in isooctane. This product is essential for environmental monitoring, regulatory compliance testing, and quality control in analytical laboratories. It is primarily used by researchers and technicians in environmental testing, industrial hygiene, and forensic analysis who require precise and reliable calibration standards for gas chromatography (GC) or gas chromatography-mass spectrometry (GC-MS).

Application

• Environmental Analysis: Calibration and quantification of PCB contamination in soil, water, sediment, and air samples for regulatory compliance (e.g., EPA methods).
• Industrial Hygiene Monitoring: Used as a standard for analyzing workplace air and surface wipe samples to ensure occupational safety limits are not exceeded.
• Food and Feed Safety Testing: Calibration standard for detecting and quantifying PCB residues in agricultural products, seafood, and animal feed.
• Waste Characterization: Essential for identifying and quantifying Aroclor 1248 in hazardous waste streams, supporting proper disposal and remediation efforts.
• Forensic and Material Analysis: Reference material for identifying the source of PCB contamination in building materials (e.g., caulking, paints) and electrical equipment.
• Method Development and Validation: Serves as a critical component in developing, optimizing, and validating new analytical methods for PCB detection.
• Quality Assurance/Quality Control (QA/QC): Used for preparing control charts, spike recovery tests, and instrument performance verification in accredited testing laboratories.

Quality Control

This analytical standard is produced under strict quality control protocols to ensure accurate concentration, purity, and stability. Each batch is analyzed against certified reference materials using validated methods such as GC-FID/ECD or GC-MS. A comprehensive Certificate of Analysis (COA) is provided, detailing the exact concentration, solvent verification, and analytical method used. Our quality system is designed to support ISO/IEC 17025 accredited laboratories and compliance with global regulatory frameworks like EPA, REACH, and POPs regulations.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to the highly volatile nature of the isooctane solvent, ensure caps are securely tightened after each use to prevent evaporation and concentration change. For long-term stability, storage under inert atmosphere (e.g., nitrogen) in the original sealed vial is recommended.
