提高了HPLC系統的分離效率、方法穩定性和分析通量；在低pH條件下的極長柱壽命
XSelect HSS C18 柱是超高效通用性C18色譜柱，用于提供對堿性分析物的優異峰形、提高保留(相對于BEH C18柱)，以及在低pH條件下的極長柱壽命。XSelect HSS C18 柱所表現出的選擇性與保留性與大多數現代全封端的硅膠C18色譜柱色譜行為較為相近。
市售低PH流動相條件下的鍵合相，不會像舊的鍵合相一樣有峰型很差的問題，這點依靠的是一種立體的保護來確保低PH條件下的穩定性。
沃特世很清楚顆粒基質在色譜選擇性和保留特性方面所起的作用：沒有單種顆粒基體能夠滿足所有的色譜分析挑戰。 另外，鍵合到不同基體上的同一配體也能產生各種不同的色譜結果。高強度硅膠 [HSS] 技術的開發專門用于與疏水性更 強的 BEH 和 CSH 顆粒的色譜性能相互補。與含亞乙基橋的 BEH 和 CSH 顆粒相比，HSS 顆粒更強的硅醇基活性（99% 硅膠） 可提供明顯的色譜優勢，包括增加極性化合物的保留和顯著的選擇性差異。另外，正如名字所示，HSS 顆粒被設計和合 成用于可承受 UPLC 壓力所需的機械強度。
Development and validation of new RP-HPLC method for the determination of gliclazide in tablet dosage form
A new sensitive and economic analytical method for the analysis of gliclazide in tablet dosage form was developed and validated using commercial HPLC instrument with modern ultra-performance liquid chromatography column. Samples were analysed using Agilent 1100 Series RP-HPLC equipped with a binary pump and auto injector. Samples were injected into Xselect HSS C18 XP column (2.1 × 100 mm, 2.5 μm), 2.5 μm) and the phase consisted of triethylamine buffer 0.3% (pH = 3 adjusted using phosphoric acid) and acetonitrile in the ratio of 50:50 v/v. The flow rate was 0.4 mL/min and the DAD detector was used for the detection and the wavelength was 229 nm. The method was validated according to ICH guidelines. The retention time for gliclazide peak was 3.437 ± 0.41 min with the total run time of 6 min with total solvent consumption of 2.4 mL per run. The method was found linear over the range 0.1-10 μg/mL with coefficient of determination R2 of 0.9997. The recovery was 98.09-100.19 %, and the method showed high precision and repeatability. Degradation pathway of gliclazide was studied following different types of stress degradation which are base, acid, UV, and oxidization. All validated parameters were in the acceptable range of ICH requirements. In conclusion, a new, rapid, sensitive, and economic method was developed and validated for the analysis of gliclazide in tablet dosage form. ? 2017, Colegio de Farmaceuticos de la Provincia de Buenos Aires.
