Abstract Content
Nowadays, reversed-phase chromatography has an important role in precise purification of high value-added compounds, such as natural products and pharmaceutical peptides or proteins. In the field of industrial scale purification by reversed-phase chromatography, improvement of cost effectiveness is very meaningful.

There has been much attention given to organic/inorganic hybrid silica based gel in order to improve the chemical stability at expanded pH and temperature, especially in the analytical HPLC field. This chemical stability of hybrid silica is considered useful as the packing materials for preparative HPLC, because it provides greater flexibility in method development and also allows the effective cleaning of the gel with alkaline solution which is often required in purification of peptides and proteins.

We have successfully prepared the new hybrid silica based packing material, named YMC-Triart Prep, by using microreactor technology for precise granulation and novel surface modification technology for higher performance and chemical stability. YMC -Triart Prep provides enhanced efficiency and increased column lifetime compared to conventional silica based material, and these result in cost-effective purification of high value-added compounds.

In this poster, we will show characteristics and advantages of this new YMC-Triart Prep material, including mechanical stability by repacking evaluation, and chemical stability under cleaning-in-place condition with alkaline solution. And we will also introduce some examples of purification of peptides and natural products utilizing characteristics of this material.
