Kromasil是瑞典AKZO NOBEL公司生产的高性能硅胶基质液相色谱柱填料品牌。 Kromasil是一种高纯度球形硅胶填料，金属杂质含量极低，减少了有些金属螯合物在硅胶基质上的络合作用。 Kromasil硅胶的表面由独特的硅羟基基团组成，硅烷的覆盖率高，在较高的或较低的PH条件下不易水解和分解，可在PH=1.5～9.5条件下稳定使用。 Kromasil的含碳量高，表面极性小，分离效能高。通常在分析碱性样品时，与酸性硅羟基反应会产生不利的拖尾现象，而Kromasil化学纯度极高，它的表面由分布独特、相对中生的硅羟基基团组成，并使不需要的酸性硅羟基基团减少到最低，从而使之具有良好的峰对称性种较高的柱效。

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.
