     EF-C18是新推出的通用型反相色譜柱，采用了高純度、高機械強度的硅膠基質(zhì)，十八烷/基鍵合相按鍵合工藝所獲得的碳含量的高低，分為高碳（C18-H）、中碳（C18-M）兩大類，以適合用戶在不同應(yīng)用范圍的需求；另外C18-Xtra型由于特有的硅膠表面處理工藝，具有更為出眾的穩(wěn)定性，更寬的pH使用范圍（1.5~10.0）和優(yōu)異的峰型。

   EF-C18Bio是以300A大孔徑硅膠為基材的液相色譜柱。通過采用改進的高密度鍵合技術(shù)及完全封尾，使得它們非常適合分離和純化從低分子量至中、高分子量的各類化合物，尤其像胰島素等多肽和蛋白質(zhì)等生化樣品。超低的表面硅醇基活性及金屬含量，使峰型對稱且無對蛋白質(zhì)的非特異性吸收，從而保證蛋白質(zhì)等樣品分析準(zhǔn)確性。另外在耐酸性和耐堿性方面的明顯改進，使其能夠應(yīng)用于酸性流動相條件和用含NaOH的緩沖溶液進行柱清洗。
