cis/trans FAMEs<br />
Rt®-2560 Column (fused silica)<br />
(highly polar phase; biscyanopropyl polysiloxane—not bonded)<br />
• Application-specific column for cis/trans FAMEs.<br />
• Stable to 250 °C.<br />
Because the Rt®-2560 stationary phase is not bonded, it should not be solvent rinsed.<br />
