Daily testing for DDT and endrin degradation, a requirement of US EPA Methods 508/508.1, 608, 617, 625, 1618, 1656, 8080A/8081, 8250A/8270B, and CLP, typically is performed by injecting the calibration mix and checking for degradation products. Because we designed this reference material specifically for degradation testing, it provides better quality control.
4,4'-DDT (50-29-3), 200 µg/mL
Endrin (72-20-8), 100 µg/mL
