シリカゲル粉末は、凝集構造を形成するコロイド粒子で構成された、固体特性を備えたコロイド系です。コロイド粒子は、アモルファス物質である水和シリカゲルの縮合ポリマーです。コロイド粒子の凝集体のギャップは、試薬カラムクロマトグラフィー用のシリカゲル粒子の内部に微孔性構造を形成します。そのため、ミクロポーラス構造が豊富で、比表面積が大きく、純度が高く、活性が高い高品質の吸着材料です。
シリカゲルパウダー has good thermal stability and chemical stability. It can selectively adsorb and purify isomer components from multi-component solutions. In the process of preparing シリカゲル粉末, a series of products with an average pore diameter of 20A°-20000A° can be produced by controlling different process conditions to adapt to the separation and purification of substances with different properties, molecular weights and molecular structures. The purity of シリカゲル粉末 is as high as 99%. Compared with organic column packing, silica gel is a solid colloid with SiO2 as the matrix, and has a compact structure. Even if it is directly discarded, organic matter will be lost and the target product will be contaminated.
