Rtx®-1614 Columns
(fused silica)
(5% diphenyl, 95% dimethyl polysiloxane)
• Optimized for PBDE analysis by EPA Method 1614.
• Short column option resolves BDE-209 3 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.
• Stable to 360 °C.
