2,2′,4,4’,6,6’-Hexachloro-1,1’-biphenyl

PCB 155 (CAS 33979-03-2) reference standard supports robust LC-MS/MS and GC-MS quantification across environmental and food matrices. This polychlorinated biphenyl reference material is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It enables traceable calibration and consistent method performance from initial screening to confirmatory analysis.

Each lot is manufactured to high purity and supported by comprehensive characterization data. You receive clear information for traceability, including lot number, intended use, and storage guidance. The reference standard is optimized for accurate calibration curves, spike-recovery experiments, and matrix-matched validation. As a result, you gain precise, repeatable results across instruments and workflows. Moreover, it integrates smoothly into multi-residue methods.

• Calibration: build stable, linear calibration curves for LC-MS/MS and GC-MS.
• Method validation: verify selectivity, accuracy, precision, and measurement uncertainty.
• Traceability: link results to well-documented production and lot data.
• Confirmatory analysis: substantiate findings with independent levels and bracketing.
• Quality control: monitor instrument performance and drift over time.

• Regulated laboratories performing routine compliance testing.
• Pharmaceutical research requiring clean reference materials for studies.
• Residue control programs in food, feed, and environmental monitoring.
• Metabolism studies needing reliable quantification of chlorinated biphenyls.
• Multi-residue method development with complex matrices and coeluting analytes.

Use PCB 155 (CAS 33979-03-2) to prepare gravimetric stock solutions and working levels. Apply it for external calibration, bracketing, and independent confirmation of positive findings. It supports ruggedness testing and verification of detection and quantification limits. With documentation from WITEGA Laboratorien Berlin-Adlershof GmbH, you maintain solid audit trails and dependable method traceability. Choose this reference standard to streamline quantification, reduce uncertainty, and improve confidence in critical decisions.
