PCB 209

Decachloro-1,1’-biphenyl

The PCB 209 (CAS 2051-24-3) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH enables confident identification and quantification in complex matrices. As a congener-specific calibration standard, it supports routine screening and targeted assays in LC-MS/MS and GC-MS. Laboratories benefit from consistent performance, clear traceability, and robust analytical outcomes from sample to report.

This reference standard is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH with comprehensive batch documentation. Therefore, it provides traceable calibration and harmonized reporting across projects and sites. Use it to establish linear ranges, verify selectivity, and confirm compound identity with matched retention and ion ratios.

• Quantitative LC-MS/MS and GC-MS calibration with excellent reproducibility
• Traceability for method transfer and inter-lab comparability
• Method validation: accuracy, precision, LOQ, and recovery studies
• Confirmatory analysis with retention time and qualifier ion criteria

Typical applications extend across regulated and research environments. It supports environmental residue control, food and feed testing, and multi-residue method development. Additionally, it fits metabolism studies and matrix-matched calibration where selectivity matters.

• Regulated laboratories performing compliance monitoring
• Pharmaceutical and contract research evaluating exposure and risk
• Residue control programs in environmental, food, and feed testing
• Metabolism and degradation pathway investigations
• Multi-residue method development requiring congener specificity

Each lot ships with a detailed certificate to document identity and purity for audit-ready records. Moreover, PCB 209 reference standard supports ongoing system suitability checks and routine verification, helping you maintain data integrity and reduce rework. Choose the dependable standard designed for modern LC-MS/MS and GC-MS workflows.
