Dionex IonPac CS18 陽離子交換柱 062878

利用 Thermo Scientific? Dionex IonPac CS18 陽離子交換柱分離極性胺。 該款低容量、帶羧酸鹽官能團(tuán)的色譜柱專為使用簡單水性淋洗液在升高溫度下分離常見陽離子、極性小分子胺和中等疏水性的多價(jià)陰離子進(jìn)行優(yōu)化。 不過，新款 Thermo Scientific? Dionex? IonPac? CS19 或 Dionex IonPac CS19-4μm 陽離子交換柱是這些應(yīng)用的推薦色譜柱。

描述

利用抑制型和非抑制型電導(dǎo)檢測器進(jìn)行陽離子和胺分離

• 低容量色譜柱經(jīng)優(yōu)化，適用于極性胺、中等疏水性胺和多價(jià)陽離子的等度和梯度分離

• 可以配合抑制型和非抑制型電導(dǎo)檢測器使用

• 對于銨或弱堿，推薦使用非抑制型電導(dǎo)檢測器以擴(kuò)展校準(zhǔn)線性

• 也可用于 Dionex IonPac SCS-1 柱支持的多種非抑制型應(yīng)用，但柱穩(wěn)定性更佳

• 經(jīng)優(yōu)化，可輕松用于酸性梯度分離，基線漂移極小

• 低容量便于中等濃度的酸淋洗液將多價(jià)陽離子洗脫出來

• 與適量有機(jī)溶劑相容（不包括醇類），以增強(qiáng)分析物溶解度，優(yōu)化柱選擇性，或者便于有效的柱清潔

提供多種規(guī)格，實(shí)現(xiàn)應(yīng)用靈活性

• 2x250mm 分析柱

• 2x50mm 保護(hù)柱

• 更長的 250 mm 柱，實(shí)現(xiàn)更復(fù)雜樣品基質(zhì)的更高分辨率分離

• 更小柱內(nèi)徑，提高質(zhì)量靈敏度，節(jié)省洗脫液和試劑，并且降低運(yùn)行成本

Dionex IonPac CS18 陽離子交換柱

Low-Capacity Cation-Exchange Column for the Separation of Polar Amines

The IonPac^? CS18 carboxylate-functionalized cation-exchange column is tailored for the separation of polar amines including alkanolamines and methylamines, and moderately hydrophobic and polyvalent amines including biogenic amines and alkyl diamines, using simple aqueous eluents and elevated temperature. The CS18 is ideally used with RFIC systems for automatic methanesulfonic acid eluent generation.

• For amines including alkanolamines and methylamines in diverse sample matrices

• For moderately-hydrophobic amines including biogenic amines, alkyl diamines, and polyvalent amines

• Optimized for simple acidic gradient separations with minimal baseline shift

• Ideal Reagent-Free electrolytic suppression with the Cation Self-Regenerating Suppressor CSRS^? 300

• Compatible with moderate amounts of organic solvents, excluding alcohols

• Requires only a modest acid concentration to elute polyvalent cations

The IonPac CS18 cation-exchange column supports isocratic and gradient separations of polar amines, moderately hydrophobic amines, and polyvalent cations using suppressed conductivity detection. The CS18 column with nonsuppressed conductivity detection is recommended when extended calibration linearity for ammonium or weak bases is required. The CS18 can be used for many of the nonsuppressed applications supported by the IonPac SCS-1 column but with much greater column stability.

The IonPac CS18 is targeted for analysis of power plant waters treated with ammonium, morpholine, or ethanolamine; chemical additives; chemical process solutions; scrubber solutions; personal care products; and food samples.

Note: Use the Cation Self-Regenerating Suppressor (CSRS 300) with the CS18 column.
