Kromasil是瑞典AKZO NOBEL公司生產(chǎn)的高性能硅膠基質(zhì)液相色譜柱填料品牌。 Kromasil是一種高純度球形硅膠填料,金屬雜質(zhì)含量極低,減少了有些金屬螯合物在硅膠基質(zhì)上的絡(luò)合作用。 Kromasil硅膠的表面由獨(dú)特的硅羥基基團(tuán)組成,硅烷的覆蓋率高,在較高的或較低的PH條件下不易水解和分解,可在PH=1.5~9.5條件下穩(wěn)定使用。 Kromasil的含碳量高,表面極性小,分離效能高。通常在分析堿性樣品時(shí),與酸性硅羥基反應(yīng)會產(chǎn)生不利的拖尾現(xiàn)象,而Kromasil化學(xué)純度極高,它的表面由分布獨(dú)特、相對中生的硅羥基基團(tuán)組成,并使不需要的酸性硅羥基基團(tuán)減少到最低,從而使之具有良好的峰對稱性種較高的柱效。
Separation Products is a department within Eka Chemicals, a global company with 2,900 employees in 30 countries. Eka Chemicals is a business unit within AkzoNobel, one of the world’s largest chemical groups, with about 61,500 employees in more than 80 countries.
The Separation Products group, or the Kromasil team, is a group of people with skills in a wide range of areas. We are dedicated to our mission to develop outstanding packing materials for HPLC, to improve efficiency and decrease costs in your separation step.
When the first Kromasil silica-based packing materials were introduced in the market, they greatly improved the effectiveness of liquid chromatography. What made the new packing material so unique was the combination of high pore volume and surface area, together with a very high mechanical stability. Even today this combination of properties is unmatched by other chromatography packings on the market.
