Description

2,2',3,3',4,4',5,5'-Octacb (Pcb-194) (13C12, 98%) 40+/-2 Ug/Ml In Nonane is a high-purity, stable-isotope labeled analytical standard, specifically formulated as a solution in nonane for precise quantitative analysis. This product is essential for laboratories requiring the highest level of accuracy in trace-level detection and quantification of polychlorinated biphenyls (PCBs). It is primarily used by environmental testing laboratories, regulatory agencies, and research institutions engaged in method development, calibration, and quality control for persistent organic pollutant (POP) monitoring.

Application

• Internal Standard for GC-MS/MS Analysis: Used as a quantitative reference for the analysis of PCB-194 and related congeners in complex matrices.
• Method Development and Validation: Critical for establishing and verifying the accuracy, precision, and detection limits of analytical methods for PCBs.
• Instrument Calibration: Serves as a primary or secondary calibration standard for gas chromatography systems coupled with mass spectrometry (GC-MS) or electron capture detection (GC-ECD).
• Quality Assurance/Quality Control (QA/QC): Employed in spike/recovery studies and as a continuing calibration verification (CCV) standard to ensure ongoing data integrity.
• Environmental Monitoring: Analysis of soil, sediment, water, and biota samples for regulatory compliance and environmental impact assessments.
• Food and Feed Safety Testing: Detection and quantification of PCB residues to ensure compliance with international safety standards.
• Research on PCB Metabolism and Fate: Utilized in tracer studies to investigate the environmental transport, degradation, and bioaccumulation of PCBs.

Quality Control

Every batch of this analytical reference material is manufactured and verified under strict quality protocols. The concentration and isotopic purity are confirmed against certified reference materials using high-resolution mass spectrometry. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing the exact concentration, purity, solvent verification, and analytical method data. Our quality system is designed to meet the rigorous demands of ISO/IEC 17025 accredited laboratories and global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). The solution is provided in nonane, which is highly flammable; keep away from heat, sparks, and open flame. For long-term stability, storage at -20°C is recommended.
