能耐受二甲基亞砜（DMSO）溶劑，在純化堿性化合物時，一次進樣量增加六十倍。
基于代雜化顆粒技術的 XTerra® 系列高效液相色譜柱, 可以讓色譜工作者在藥物發現，方法開發和純化分離領域使用高pH值流動相。
§ XTerra顆粒能耐受二甲基亞砜（DMSO）溶劑，可延長高通量藥物發現研究中色譜柱的壽命。
§ 寬pH 范圍使得方法開發研究人員在所需的pH值條件下操作，以獲得性。
§ 高載荷量使得分離純化的科學家在高pH值條件下，在純化堿性化合物時，一次進樣量增加六十倍。
XTerra® MS、Shield RP和苯基色譜柱將硅膠和聚合物鍵合相的性能與的雜化顆粒技術相結合，在顆粒合成中每三個硅 烷醇中有一個被替換成甲基基團。這個步驟只能在顆粒合成的 起始階段完成，加入的此甲基基團是堿性顆粒骨架的組成部分。 由此可生成機械強度大的顆粒，適用于高pH值條件下的分離，提 高堿性化合物的上樣量和峰形。
XTerra® RP18和RP8色譜柱將內嵌極性基團的屏蔽技術與雜化顆粒技術結合起來，可以獲得對稱的色譜峰形。這一通用型色譜柱以的選擇性為快速方法開發提供了一個強有力的工具。同其它所有XTerra® 色譜柱一樣，利用屏蔽技術的XTerra® RP色譜柱展現了極其優秀的水浸潤性，即便是使用99%的水溶液作為流動相，亦可獲得穩定的色譜結果。大大拓寬的pH范圍，為選擇性調節提供了有效途徑；加上選擇性互補的MS和RP兩種鍵合相更是增加了選擇性的調節范圍，是成功進行方法開發的工具。
A simple method is presented for the simultaneous determination of morphine, 6-acetylmorphine, codeine, cocaine, benzoylecgonine, cocaethylene, methadone and 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) in vitreous humor by high-performance liquid chromatography with photodiode array detector after solid-phase extraction with Oasis® HLB cartridges and dichloromethane as eluent. The chromatographic process was carried out using an XTerra® RP8 column (250 × 4.6 mm i.d., 5 µm particle size) and a phase composed of acetonitrile and pH 6.5 phosphate buffer in gradient mode. A linear response from the detector was obtained within the concentration range of 0.1-4 µg ml(-1) , with correlation coefficients higher than 0.99. The limits of detection were lower than 30 ng ml(-1) for all the drugs studied, the coefficients of variation fluctuated between 0.1 and 12.4%, and the average recoveries were higher than 78% for all the drugs except for EDDP, with a value of 66.4%. Finally, the proposed method was applied to 15 vitreous humor samples coming from individuals who had died from opiate and/or cocaine overdose, showing consumption of cocaine in 14 cases, methadone in five cases and in three cases. Average concentrations of 0.30 µg ml(-1) for morphine, 0.24 µg ml(-1) for 6-acetylmorphine, 0.10 µg ml(-1) for codeine, 0.81 µg ml(-1) for cocaine, 1.26 µg ml(-1) for benzoylecgonine, 0.15 µg ml(-1) for cocaethylene, 0.11 µg ml(-1) for methadone and 0.68 µg ml(-1) for EDDP were obtained.
