       Hypersil BDS 類色譜填料是*的反相柱填料，有很好的耐久性及重現(xiàn)性，應(yīng)用范圍極其廣泛。Hypersil BDS硅膠擔(dān)體鍵合前經(jīng)過專門的堿鈍化處理，將殘余硅羥基降限，這種改善的表面，使得鍵合后的硅膠具有很高的配位度，大大降低了硅羥基與分析物的之間的相互作用，改善了色譜峰型，降低了色譜峰的拖尾程度，提高了峰的對(duì)稱性。
        由于化學(xué)共價(jià)鍵的重現(xiàn)性，使Hypersil BDS色譜柱即使在強(qiáng)酸條件下也有很長(zhǎng)的柱壽命。Hypersil BDS色譜柱填料有粒度為3和5μm兩種，其中3 μm比5 μm柱效高25%。由于分離度的提高，使用短的快速分析柱也可獲得同樣的分離，窄孔柱可提高靈敏度。
Hypersil BDS色譜柱鍵合相有C18、C8、苯基和氰基四種，廣泛用于酸、堿和中性樣品的分析，對(duì)于酸和堿可得到相似的結(jié)果，且峰形均很好。Hypersil BDS苯基色譜柱的選擇性與C18（ODS）相反。分析堿性藥物時(shí)，Hypersil BDS苯基柱得到的峰形。Hypersil BDS Cyano柱用于反相時(shí)選擇性也與Hypersil BDS C18 柱及Hypersil BDSC8柱不同。另外，Hypersil BDS Cyano柱可用于正相色譜。
