Highly polar, non-bonded biscyanopropyl polysiloxane phase. Selectivity optimized for isomer separation to ensure accurate quantification of critical cis/trans FAMEs. Temperature range: 20 °C to 250C. Similar phases: Phenomenex ZB-FAME, Quadrex: SLP-2560, Supelco/Millipore Sigma SP-2560, Restek Rt-2560. NOTE: due to the non-bonded phase, 2560 columns should not be solvent rinsed.
