2,2′,3,4,5,6’-Hexachloro-1,1’-biphenyl

PCB 143 (CAS 68194-15-0) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH for LC-MS/MS and GC-MS workflows. As a residue analysis standard for environmental and food matrices, it supports reliable calibration and traceable quantification. Therefore, laboratories can implement consistent monitoring with confidence and clarity.

This material enables precise quantification, robust calibration, and full method validation. You can confirm results confidently in complex matrices. Moreover, its specification supports traceability throughout the analytical chain and simplifies documentation during audits.

• LC-MS/MS and GC-MS calibration for linearity, range, and LOQ
• Traceability aligned with documented purity and uncertainty
• Method validation: accuracy, precision, selectivity, and recovery
• Confirmatory analysis in food, environmental, and industrial samples

Typical users include regulated laboratories, residue control programs, and contract testing facilities. Pharmaceutical research teams apply it in metabolism studies and in multi-residue method development where selectivity matters. Additionally, academic and governmental labs use it to harmonize inter-laboratory comparisons and to ensure result comparability over time.

WITEGA Laboratorien Berlin-Adlershof GmbH supplies PCB 143 (CAS 68194-15-0) with a comprehensive Certificate of Analysis to support documentation needs. The reference standard is suitable for solution preparation in organic solvents and for routine system suitability checks. Furthermore, it integrates smoothly into LC-MS/MS or GC-MS quantitative workflows for screening and confirmatory analysis. Store as recommended on the CoA and handle under clean conditions to avoid contamination.
