Rtx®-65TG Columns (fused silica)<br />
(high polarity phase; Crossbond® 65% diphenyl/35% dimethyl polysiloxane)<br />
• Application-specific <strong>columns</strong>, specially tested for triglycerides.<br />
• Stable to 370 °C.<br />
The Rtx®-65TG phase resolves triglycerides by degree of unsaturation as well as by<br />
carbon number. Because of the chemistry required to achieve 370 °C thermal stability,<br />
an Rtx®-65TG column should not be used for the analyses of polar compounds.<br />

Sharp resolution of butter triglycerides on an Rtx®-65TG column.<br />
Column: Rtx ® -65TG, 30m, 0.25mm ID, 0.10µm (cat.# 17008)<br />
Sample: 0.2µL cold on-column injection of 1% butterfat in isooctane<br />
Oven temp.: 80°C (hold 1 min.) to 240°C @ 30°C/min.<br />
to 360°C @ 4°C/min. (hold 5 min.)<br />
Det. temp.: 380°C<br />
Carrier gas: hydrogen<br />
Linear velocity: 70cm/sec.<br />
FID sensitivity: 16 x 10 -11 AFS<br />
SPI injector: high performance capillary insert 60°C,<br />
300°C/min. to 400°C (hold 5 min.)<br />
please note<br />
Triglycerides are often injected via on-column<br />
injection. Use 0.53 mm retention gaps and<br />
appropriate connectors.<br />
