Dibenzyl disulfide (DBDS) is a corrosive sulfur compound that can accelerate copper sulfide formation in transformers, increasing the risk of insulation damage and equipment failure. Routine monitoring of DBDS is therefore critical for transformer health, regulatory compliance, and preventive maintenance. This application note demonstrates how the PerkinElmer GC 2400 System with Electron Capture Detection (ECD) provides a sensitive, reliable, and cost-effective approach for DBDS analysis in transformer oils, delivering excellent linearity, precision, and freedom from carryover in accordance with IEC 62697 guidelines.
