Welch Materials / Ultisil

Ultisil

Ultisil™ HPLC columns are manufactured by Welch Materials Inc., located in Shanghai, China.

The phases are based on high-purity spherical silica gel, which is available in many different modifications for a wide selectivity range. Ultisil™ columns show high reproducibility, long lifetime and excellent peak shape for many compounds.

Ultisil AAA and PAH are application specific HPLC columns for the separation of amino acids and polyaromatic hydrocarbons, respectively.

Ultisil™ODS-3 HPLC Columns are a water-resistant C-18 phase with broad applicability. The stationary phase is strictly endcapped with hydrophilic groups and shows low adsorption for both basic and acidic compounds.
