Develosil TMS,UG, C8-UG, Ph-UG, CN-UG
The effect of the double end cap can solve the problems of the conventional residual silanol group and is not exaggeration even if I say the current mainstream.

Use is various. It is a part to a separation improvement.
Composition is adjusted so that ethylbenzene may be eluted to 8.5min. The hydrophobicity of a column is in a high tendency, so that a methanol ratio is high.
Separation comparison by a standard sample
Develosil C8-UG-5 becomes the same elution order as an ODS column. Retention turns into retention equivalent to an alkyl chain. The sequence which TMS-UG, Ph-UG, and CN-UG elute differs. And a peculiar result is drawn. Since an elution order is changeable in a column even if it is the same reversed phase system, the width of a use is expanded.
Separation comparison of capsaicin
The example of separation of the capsaicin by the same terms. It is in the tendency which shows such strong retention that hydrophobicity is high. Although capsaicin is analyzed in Ph column in many cases, also in ODS with hydrophobicity, or C30, analysis is possible.
