Product Overview
Aroclor 1242 is a high-purity polychlorinated biphenyl (PCB) standard solution designed for precise analytical applications. This certified reference material contains 1000 µg/ml of Aroclor 1242 dissolved in hexane, offering exceptional stability and accuracy for environmental testing and industrial analysis. The analytical-grade formulation ensures minimal interference, making it ideal for gas chromatography (GC) and mass spectrometry (MS) applications where trace-level detection is critical. Each batch undergoes rigorous quality control to guarantee consistency, with detailed certification provided for traceability. The hexane solvent is carefully purified to prevent contamination, ensuring reliable results in sensitive testing environments. This standard is particularly valuable for laboratories conducting PCB monitoring in soil, water, or biological samples, where regulatory compliance and data integrity are paramount. The 1 ml pack size provides an optimal balance between cost efficiency and sufficient volume for repeated calibrations or method validations.
FAQs
1. What is the shelf life of Aroclor 1242 standard in hexane?
The shelf life is typically 24 months when stored unopened at the recommended temperature. Always check the certificate of analysis for batch-specific expiration dates.
2. Can this standard be used for GC-MS analysis?
Yes, this Aroclor 1242 standard is specifically formulated for GC-MS applications, providing consistent response factors and minimal matrix interference.
3. What precautions should be taken during storage?
Store the unopened vial at 2-8°C, protected from light. Once opened, use immediately and avoid prolonged exposure to air to prevent solvent evaporation.
4. Is this standard compatible with EPA methods for PCB analysis?
This standard meets the requirements for EPA methods 1668 and 8082, making it suitable for environmental PCB testing protocols.
5. What alternatives are available if this concentration is too high?
Lower concentration standards (e.g., 100 µg/ml or 10 µg/ml) are available for applications requiring more dilute reference materials.
