Description

Pcb 52-13C12 is a carbon-13 labeled isotopologue of Polychlorinated Biphenyl congener 52 (2,2',5,5'-Tetrachlorobiphenyl), a critical compound for advanced analytical and research applications. This stable isotope-labeled standard is essential for achieving high-precision quantification and reliable trace analysis in complex matrices. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions engaged in method development, quality control, and regulatory compliance studies for persistent organic pollutants.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a crucial quantitative internal standard in GC-MS and LC-MS/MS analysis for accurate determination of native PCB-52 and related congeners.
• Environmental Monitoring and Analysis: Used in the testing of soil, water, sediment, and biota samples to track PCB contamination and assess environmental remediation efforts.
• Food and Feed Safety Testing: Employed in analytical methods to quantify PCB residues, ensuring compliance with strict international food safety regulations.
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical protocols for PCB detection with high accuracy and low detection limits.
• Quality Assurance/Quality Control (QA/QC): Acts as a reference material in laboratory proficiency testing and for verifying the accuracy and precision of analytical instrumentation.
• Forensic Analysis: Aids in source identification and fingerprinting of PCB mixtures in environmental forensic investigations.

Quality Control

Every batch of Pcb 52-13C12 is manufactured and analyzed under strict quality management systems to ensure the highest standards of isotopic purity and chemical identity. Our products undergo rigorous quality testing, including isotopic enrichment verification by high-resolution mass spectrometry and chemical purity assessment. Certificates of Analysis (COA) are provided, detailing batch-specific results for isotopic purity, chemical purity, and concentration. We support compliance with ISO 17025, EPA methods, and other relevant regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. For long-term storage under inert atmosphere, seal under argon or nitrogen. Keep away from strong acids and organic solvents. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
