Certified PCBs (for analysis)

Certified PCBs (for analysis) is an analytical reference standard containing defined polychlorinated biphenyl congeners at traceable concentrations, produced under strict quality controls to ensure homogeneity and stability. It is widely used for instrument calibration, method development and validation, and routine QC in the determination of PCB residues by GC-ECD, GC-MS, and GC-MS/MS techniques. The material delivers reliable accuracy, precision, and lot-to-lot consistency required for regulatory and trace-level analysis. Typical users include environmental testing laboratories, food and feed safety labs, contract research organizations, and academic and government research institutions monitoring persistent organic pollutants.
