為使用鹽酸 (HCl) 和二氨基丙酸 (DAP) 淋洗液對無機陽離子進行等度分離選擇 Thermo Scientific? Dionex? IonPac? CS11 分析和保護柱。 該款色譜柱的選擇性與 IonPac CS10 柱相似,但靈敏度有所改善,且因為使用更小的 2mm 內徑規格,淋洗液用量更小。
Dionex IonPac CS11 柱可用于測定多種樣品基質中的常見無機陽離子和脂肪胺以及芳香胺,但是陽離子交換柱技術的發展使得在進行這些分離時有更好的色譜柱可供選擇。
推薦的陽離子交換柱
自*推出 Dionex IonPac CS11 柱后,Dionex 已經推出了數款包含高級功能的新型陽離子交換柱。 例如,多數現代 Dionex IonPac 陽離子交換柱使用簡單的甲磺酸淋洗液,而不是 DAP-HCl 淋洗液。 這些色譜柱及其推薦用途羅列如下。
Dionex IonPac CS12A 柱改善了快速分析多種基質中無機陽離子和銨的性能。
Dionex IonPac CS17 柱推薦用于疏水和多價胺。
Dionex IonPac CS19 和 CS19-4μm 柱推薦用于極性胺分析,包括烷醇胺和jia胺,以及中等疏水性胺和多價胺。
兼容有機溶劑以增強分析物溶解度,改變柱選擇性,或者便于有效的柱清潔

The IonPac CS11 is designed for the isocratic separation of inorganic cations using hydrochloric acid with diaminopropionic (DAP) acid eluents.
The CS11 can be used for analysis of common inorganic cations and aliphatic, cyclic, and aromatic amines.
Compatible with organic solvents.
The CS12A improves performance for fast analysis of inorganic cations and ammonium.
The CS17 column is recommended for hydrophobic and polyvalent amines.
The CS18 column is recommended for polar amines including alkanolamines and methylamines.
The CS18 is also recommended for moderately hydrophobic amines and polyvalent amines.
The CS11 is useful in determining common inorganic cations and aliphatic and aromatic amines in diverse sample matrices, including environmental and drinking waters, power plant waters treated with ammonium, soil extracts, acid digests, chemical additives, chemical process solutions, scrubber solutions, plating baths, and industrial solvents.
The CS11 has selectvitiy similar to the CS10 column, with improved sensitivity and lower eluent consumption due to its smaller 2 mm i.d. format.
Note: Use the Cation MicroMembrane Suppressor (CMMS? 300) with the CS11 column. Electrolytic suppression is not recommended with HCl and DAP eluents.
