Rtx®-65TGColumns
(fusedsilica)
(highpolarityphase; Crossbond® 65%diphenyl/35%dimethyl polysiloxane)
• Application-specific columns, specially tested for triglycerides.
• Stable to370 °C.
The Rtx®-65TG phase resolves triglycerides by degree of unsaturation as well as by
carbonnumber. Because of the chemistry required to achieve 370 °C thermal stability,
anRtx®-65TG column shouldnot beused for the analyses of polar compounds.
