Dionex IonPac CS19-4μm 陽(yáng)離子交換柱

使用新型 Thermo Scientific? Dionex? IonPac? CS19-4μm 毛細(xì)管柱、分析柱和保護(hù)柱，可在色譜分析速度和高分辨率之間達(dá)到*平衡。 這種高載量、高分辨率并帶有羧酸鹽官能團(tuán)的色譜柱可對(duì)常見(jiàn)陽(yáng)離子、小分子極性胺以及復(fù)雜樣品基質(zhì)（如：使用氨、嗎啉或乙醇胺處理過(guò)的發(fā)電廠廢水、化學(xué)添加劑、化學(xué)加工溶液、洗滌液、個(gè)人護(hù)理品、食品樣本）中的多價(jià)胺實(shí)現(xiàn)分離。

描述

與 Thermo Scientific? Dionex? IonPac? CS19 色譜柱相比，這種色譜柱使用更小的樹(shù)脂顆粒以提高分離效率，從而提高峰積分的準(zhǔn)確度并獲得更可靠的結(jié)果。

對(duì)各種基質(zhì)內(nèi)的常見(jiàn)陽(yáng)離子和小分子極性胺實(shí)現(xiàn)zui高分辨率的分離

• 通過(guò)使用更小的樹(shù)脂顆粒，可對(duì)復(fù)雜樣品基質(zhì)內(nèi)的常見(jiàn)陽(yáng)離子和小分子極性胺實(shí)現(xiàn)zui高分辨率的分離

• 峰效率提高且分辨率增加，從而實(shí)現(xiàn)更加*的積分并獲得更可靠的結(jié)果

• 由于選擇性相似，因此可將基于 Dionex IonPac CS19 柱的應(yīng)用輕松轉(zhuǎn)移至 4 μm 柱

• 可對(duì)小分子極性胺（包括鏈烷醇胺和jia胺）以及中等疏水性胺和多價(jià)胺（包括生物胺和烷基二胺）進(jìn)行簡(jiǎn)單梯度分離

• 高載量便于進(jìn)樣高濃度樣品，同時(shí)不會(huì)導(dǎo)致柱過(guò)載或峰展寬

• 與適量有機(jī)溶劑相容（不包括醇類），從而可增強(qiáng)分析物的溶解度，改變柱選擇性，并且有助于有效清潔色譜柱

配合高壓離子色譜系統(tǒng)使用
通過(guò)使用更小的樹(shù)脂顆粒，可達(dá)到更高的分辨率，并在標(biāo)準(zhǔn)流速下產(chǎn)生超過(guò) 3000 psi 的柱反壓。 一臺(tái)高壓離子色譜系統(tǒng)（如：Thermo Scientific? Dionex? ICS-5000+ HPIC? 或 Dionex ICS-4000 Capillary HPIC 系統(tǒng)）是在標(biāo)準(zhǔn)條件下運(yùn)行該色譜柱并發(fā)揮流速高和運(yùn)行時(shí)間短等優(yōu)勢(shì)的必要設(shè)備。

洗脫液需要量減少，從而降低了運(yùn)行成本
由于使用相同的填料，因此 Dionex IonPac CS19-4μm 毛細(xì)管柱可提供與標(biāo)準(zhǔn)孔和微孔 Dionex IonPac CS19-4μm 柱相同的性能。 由于毛細(xì)管系統(tǒng)運(yùn)行的洗脫液流速僅為標(biāo)準(zhǔn)孔系統(tǒng)的 1%，需要的洗脫液更少，產(chǎn)生的廢物也更少，從而降低運(yùn)行成本。

提供多種規(guī)格，實(shí)現(xiàn)應(yīng)用靈活性

• 4x250 mm、2x250 mm 分析柱

• 4x50 mm、2x50 mm 保護(hù)柱

• 0.4x250 mm 毛細(xì)管柱、0.4x50mm 毛細(xì)管保護(hù)柱

• 更長(zhǎng)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

High Resolution, High-Capacity Cation-Exchange Column for the Separation of Small Polar Amines

Attain the optimal combination of chromatographic speed and resolution using the new Thermo Scientific? Dionex? IonPac? CS19-4μm cation-exchange column. This high capacity, high resolution capillary column provides excellent resolution of common cations, small polar amines and polyvalent amines in complex sample matrices. Compared to the previous Dionex IonPac CS19 column, the new ion-exchange column uses smaller resin particles for more efficient separations resulting in faster analysis, more accurate peak integration, and more reliable results.

The Dionex IonPac CS19-4μm carboxylate-functionalized cation-exchange column has similar selectivity to the Dionex IonPac CS19 column for the six common cations, small polar amines (including alkanolamines and methylamines) and moderately hydrophobic and polyvalent amines (including biogenic amines and alkyl diamines). Applications run on the Dionex IonPac CS19 column can be easily transferred to the Dionex IonPac CS19-4μm column with the benefit of increased peak resolution which provides more consistent results. The Dionex IonPac CS19-4μm column is available in three formats, standard bore (4 × 250 mm), microbore (2 × 250 mm), and capillary  (0.4 × 250 mm). The capillary and microbore formats require less eluent thereby reducing operating costs.

• Increase speed, chromatographic resolution and quality of analytical results

• For analysis of amines including alkanolamines and methylamines in diverse sample matrices

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

• Optimized for fast simple acidic gradient separations with minimal baseline shift

• High capacity allows routine analysis of high-ionic-strength samples

The Dionex IonPac CS19-4μm column is targeted for analysis of power plant waters treated with ammonium, morpholine, or ethanolamine; as well as chemical additives; chemical process solutions; scrubber solutions; personal care products; and food samples.

The smaller resin particles used in the Dionex IonPac CS19-4μm column produce increased backpressure. When operating the Dionex IonPac CS19-4μm microbore or capillary column at standard flow rate, an IC system capable of operating up to 3000 psi is sufficient. However, to take advantage of the fast runs, using elevated flow rates, a high pressure IC system, such as the Thermo Scientific Dionex ICS-5000⁺ HPIC or Dionex ICS-4000 HPIC is required. The Dionex ICS-5000⁺ HPIC system is required for standard operation of the Dionex IonPac CS19-4μm standard bore column.
