Thermo賽默飛Hypersil BDS C18色譜柱自 1989 年發明以來，一直廣受業界推崇，被認為是耐用可信賴的色譜柱之一。Hypersil BDS 色譜柱以高度堿性去活硅膠為擔體，采用封端技術屏蔽硅醇基， 具有以下優點：
* 出色的重現性
* 明顯改善峰拖尾
* 十分耐用，色譜柱使用壽命較長
* 不論是堿性化合物還是酸性化合物，均呈現wan美峰形。
已廣泛應用在許多藥典方法中，例如：一枝黃花（蘆丁)、連翹（連翹酯苷A）、益母草（鹽酸益母草堿）、大黃素、小兒消食片（熊果酸）、牛黃清宮丸（黃芩苷）、風濕骨痛膠囊（鹽酸）、芎菊上清片（黃芩苷）、益母生膠囊（芍藥苷）、葛根芩連片（葛根素）等等。
為什么要用堿性去活硅膠和鍵合相？
使用共價鍵合硅膠固定相，可對多數化合物進行分離。HPLC 與液-液分配色譜相比，具有平衡速度快、分配性能更好的特點，因此，HPLC 作為現代分析手段被廣泛應用。
但是，傳統的共價鍵合硅膠固定相存在以下問題：
HPLC 中使用的建和硅膠固定相與分析物之間存在多種相互作用，這些相互作用一部分是鍵合相本身與分析物之間的作用，另一部分是鍵合時在硅膠表面殘留的硅醇基與分析物之間的作用。
硅醇基的數目和酸性極大程度影響了它與分析物間相互作用的強弱。堿性硅膠的酸-堿相互作用主要是由硅醇基產生的，硅醇基還決定了硅膠填料的表面極性。硅醇基的種類和酸性在很大程度上影響了 HPLC 的分離度和分析物的色譜峰形。
殘余硅醇基與化合物的相互作用會使酸性和堿性化合物的色譜峰產生拖尾。早期使用的 HPLC 硅膠填料，硅醇基具有很強的酸性，因此色譜拖尾現象特別明顯。
使用早期硅膠填料時，若要得到較好的色譜峰，通常需要在流動相中添加酸（醋酸）或堿（三乙胺），使其與硅醇基產生競爭性結合，從而改善色譜峰形。當使用了合適的流動相添加劑時，色譜峰形會得到明顯改善。通常需要很高的添加劑濃度多數情況下達到 1% （體積比）或更高，這樣才能使所有殘留硅醇基都與添加劑結合，而不影響分析物的色譜峰形。但是高濃度添加劑常常嚴重降低色譜柱壽命和方法重現性。
所以Hypersil BDS 是的堿性去活硅膠之一，具有以下優點：
* 減弱硅醇基相互作用
* 改善色譜峰拖尾
* 不需向流動相中加入添加劑
* 的色譜峰對稱性
* 延長色譜柱使用壽命
* 提高柱效（分析堿性、酸性、中性化合物）
Hypersil BDS重現性，批次間測試流程，多種固定相：
Hypersil BDS 色譜柱是根據最高標準生產的，并進過嚴苛的質量控制。硅膠擔體和色譜柱的生產流程均遵守 ISO9001:2000 標準。在進行鍵合前，BDS 硅膠必須通過 30 余項物理特性和色譜性能測試。在鍵合后，所有的 BDS C18 填料都經過色譜性能測試以及碳載量測試該測試在封端前和封端后各進行一次。
Hypersil BDS 色譜柱有 4 種鍵合相供選擇。所有 Hypersil BDS 色譜柱，均使用堿性去活工藝處理硅膠擔體，再經封端處理屏蔽硅醇基，即使是分析堿性化合物，也極大程度改善了峰拖尾。
