Description

3,4,4',5-Tetracb (Pcb-81) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, isotopically labeled standard solution, essential for precise analytical quantification. This product provides a critical reference for ensuring accuracy and reliability in sensitive environmental and food safety testing. It is primarily required by analytical laboratories, regulatory bodies, and research institutions engaged in trace-level contaminant analysis.

Application

• Internal Standard for Mass Spectrometry (GC-MS/LC-MS): Used for the accurate quantification of native PCB congeners in complex matrices.
• Environmental Monitoring: Calibration and quality control in the analysis of soil, sediment, water, and air samples for persistent organic pollutants (POPs).
• Food and Feed Safety Testing: Essential for regulatory compliance testing to determine PCB contamination levels.
• Method Development and Validation: Serves as a key component in establishing and verifying analytical procedures according to ISO, EPA, and other international standards.
• Certified Reference Material (CRM) Production: Acts as a primary material for formulating higher-order CRMs.
• Toxicological and Metabolic Studies: Enables precise tracking and quantification in research on the fate and behavior of PCBs.

Quality Control

Every batch of this isotopically labeled standard is manufactured and verified under strict quality control protocols to ensure identity, purity, and concentration accuracy. The 99% isotopic purity (13C12) and precise concentration (40 ± 2 µg/mL in nonane) are guaranteed. A comprehensive Certificate of Analysis (COA) is supplied with each unit, detailing results from GC-MS, NMR, and other relevant analytical techniques.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to its highly volatile solvent (nonane) and light-sensitive nature, prolonged exposure to room temperature or light should be avoided to maintain concentration and stability.
