Welch Materials / Xtimate

Xtimate

Xtimate^® HPLC columns are manufactured by Welch Materials Inc., located in Shanghai, China.

There are two types of Xtimate^® HPLC columns, those based on Hybrid Silica-Polymer packing materials, and those based on pure polymer media.

Xtimate^® hybrid phases are available with different reversed-phase modifications and show high stability and long column lifetime.

Xtimate^® SEC was developed for aqueous size exclusion chromatography. The base material is a high purity silica-gel, modified with a hydrophilic polymer and diol functional groups.

Xtimate^® G10 Glucan Gel is a special column for cephalosporine analysis.

Xtimate^® Sugar-Ca and Sugar-H are based on modified polystyrene-divinylbenzene polymer with 8% cross-linking. The columns are applicable for sugar‒ and carbohydrate analysis.

Xtimate^® PS/DVB are based on unmodified polystyrene-divinylbenzene polymer.
