SH-2560 Highly polar phase; biscyanopropyl polysiloxane—not bonded
Stationary phase selectivity optimized for isomer separation to ensure accurate quantification of critical cis/trans FAMEs.
Application-specific QC test guarantees consistent, reliable performance for AOAC 996.06 and AOCS Ce 1j-07 methods.
Excellent sample capacity; no peak distortion means easy, accurate peak integration.
