鍵合一層均勻的納米厚度中性親水薄膜而制備得到

1、 SRT SEC鍵合固定相采用專利的表面修飾技術(shù)，通過在高純度具有良好機(jī)械穩(wěn)定性的硅膠基質(zhì)上，鍵合一層均勻的納米厚度中性親水薄膜而制備得到。工藝采用可控的化學(xué)修飾技術(shù)，因此能確保柱與柱之間有著可靠的重現(xiàn)性。SRT填料采用化學(xué)鍵合技術(shù)，表面親水涂層覆蓋完全，因此不僅具有優(yōu)異的穩(wěn)定性，而且對蛋白等生物樣品的非特異性吸附作用也非常小。精心設(shè)計(jì)的大孔體積可保證高的分離容量以及優(yōu)異的分辨率。由于采用創(chuàng)新的表面化學(xué)技術(shù)，以及擁有多種孔徑規(guī)格（從100Å到2000Å），SRT SEC柱可為各種分離應(yīng)用提供最高分辨率和最大回收率。應(yīng)用領(lǐng)域覆蓋了大分子量的生物分子（如蛋白質(zhì)、核酸）、小分子量
