5% diphenyl / 95% dimethyl polysiloxane Optimized for PBDE analysis by EPA Method 1614. Short column option resolves BDE-209 three times faster, with less thermal breakdown. Unique deactivation gives higher BDE-209 response than competitor columns, for greater analytical sensitivity. Exceeds EPA Method 1614 resolution criteria for BDE-49 and BDE-71 Similar phase: Rtx-1614 Temp. Range: -60 to 330/360°C
