Description

2,3',4,4',5,5'-Hexacb (Pcb-167) (13C12, 99%) 40+/-2 Ug/Ml In Nonane is a high-purity, stable-isotope labeled internal standard solution, essential for achieving precise and reliable analytical results. This product is specifically formulated for use in advanced environmental and food safety testing, where accurate quantification of polychlorinated biphenyl (PCB) congeners is critical. It is an indispensable tool for analytical laboratories in regulatory compliance, environmental monitoring, and research sectors requiring trace-level analysis.

Application

• Internal Standard for GC-MS/GC-ECD Analysis: Primary use as a quantitative reference standard for the analysis of PCB-167 and related congeners in complex matrices.
• Environmental Monitoring: Calibration and quality control in the testing of soil, sediment, water, and air samples for persistent organic pollutant (POP) contamination.
• Food and Feed Safety Testing: Ensuring accurate measurement of PCB residues in food products, animal feed, and edible oils to comply with global safety regulations.
• Forensic and Research Laboratories: Supporting method development, validation, and high-accuracy research studies on PCB metabolism, fate, and transport.
• Waste and Industrial Effluent Analysis: Used in the assessment of industrial waste streams and remediation projects to monitor PCB levels.
• Clinical and Biomonitoring Studies: Facilitating the precise analysis of PCBs in human serum, adipose tissue, and other biological samples for exposure assessment.

Quality Control

Every batch of our 13C12-labeled PCB-167 solution is manufactured and verified under strict quality protocols to ensure the highest standard of isotopic purity (99%) and concentration accuracy (40 ±2 µg/mL). Quality is confirmed via advanced analytical techniques including GC-MS and HPLC. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing batch-specific data on identity, purity, concentration, and solvent verification.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). The nonane solvent is highly flammable; keep away from heat, sparks, and open flame. Store in a cool, well-ventilated area separate from strong acids and oxidizing agents.
