利用 Thermo Scientific? Dionex? IonPac? CS16 毛細(xì)管分析和保護(hù)柱測(cè)定多種樣品基質(zhì)中濃度差異極大的鄰近陽(yáng)離子（如鈉離子和銨離子）。 樣品基質(zhì)包括環(huán)境水樣；使用銨鹽、嗎啉或乙醇胺處理的發(fā)電廠水；化學(xué)添加劑；化學(xué)加工溶液；洗滌液；電鍍槽和工業(yè)溶劑。 Dionex IonPac CS16 柱專為用于 Thermo Scientific? Dionex? IonPac? CS15 柱多數(shù)應(yīng)用而設(shè)計(jì)，因其較大的線性工作范圍也推薦用于此類應(yīng)用。
描述
在測(cè)定差異極大的鈉離子和銨離子比例時(shí)可實(shí)現(xiàn)性能
專為測(cè)定多種樣品基質(zhì)中差異極大的鄰近洗脫陽(yáng)離子（如鈉離子和銨離子）濃度比例而優(yōu)化。

使用等度酸淋洗液，在少于 20 鐘內(nèi)分離比例zui高達(dá) 10,000:1 的鈉離子和銨離子。
使用梯度甲磺酸 (MSA) 淋洗液分離比例zui高達(dá) 20,000:1 的鈉離子和銨離子。
高容量色譜柱可改善樣品裝載量和峰分辨率
在 40?C 的*操作溫度下達(dá)到zui大峰效率
分析低 pH 值樣品的*羧酸鹽官能團(tuán)色譜柱
兼容有機(jī)溶劑（不包括乙醇），以增強(qiáng)分析物溶解度，優(yōu)化柱選擇性，便于有效的柱清潔
更低的淋洗液要求，降低運(yùn)行成本
由于使用相同的填料，Dionex IonPac CS16 毛細(xì)管柱提供的性能與標(biāo)準(zhǔn)孔和微孔 Dionex IonPac CS16 柱相同。 由于毛細(xì)管系統(tǒng)運(yùn)行的淋洗液流速僅為標(biāo)準(zhǔn)孔系統(tǒng)的 1%，需要的淋洗液更少，產(chǎn)生的廢液也更少，從而降低了運(yùn)行成本。
提供多種規(guī)格，實(shí)現(xiàn)應(yīng)用靈活性
5x250mm、2x250mm 分析柱
5x50mm、2x50mm 保護(hù)柱
0.5x250mm 毛細(xì)管柱、0.5x50mm 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)徑提供更高質(zhì)量靈敏度，節(jié)省淋洗液和試劑，從而降低運(yùn)行成本。
用途和特點(diǎn)：
IonPac CS16是高容量，羧酸功能基的陽(yáng)離子交換分離柱，用于等度分離濃度比懸殊的Na+和Li+（濃度比可達(dá)10，000：1）；以及分析復(fù)雜基質(zhì)中的短碳鏈烷基胺和烷醇胺。IonPac CS16基本適用于IonPac CS15的分析范圍。IonPac CS16柱在40℃時(shí)分離效果。有機(jī)溶劑可匹配方便清洗柱子。

High-Capacity Carboxylate-Functionalized Column for Disparate Sodium and Ammonium Concentrations
The IonPac? CS16 is the column of choice for disparate concentration ratios of adjacent eluting cations such as sodium and ammonium in diverse sample matrices. The high-capacity, high-resolution CS16 column can be used for short-chained amines, including alkylamines and alkanolamines, in diverse sample matrices. The CS16 column is now available in capillary format (0.5 × 250 mm) offering reduced eluent consumption and reduced operating costs.
For disparate concentration ratios of close-eluting cations such as ammonium and sodium in complex matrices
Ideal for trace-level ammonium in high concentrations of sodium
Ideal for trace-level sodium in high concentrations of ammonium or amines
Best carboxylate-functionalized column to tolerate samples with low pH
Isocratic acid eluent and elevated temperature (40 °C) required for sodium: ammonium ratios to 1:10,000
Gradient MSA eluent and elevated temperature required for sodium: ammonium ratios up to 1:20,000
Useful for short-chained amines, including alkylamines and alkanolamines
Compatible with organic solvents excluding alcohols
Using an isocratic acid eluent and elevated temperature (40 °C) coupled with suppressed conductivity, ratios up to 10,000:1 of sodium and ammonium can be resolved in less than 20 min. Sample matrices include environmental waters; power plant waters treated with ammonium, morpholine or ethanolamine; chemical additives; chemical process solutions; scrubber solutions; plating baths; and industrial solvents. The CS16 is designed for use in most IonPac CS15 applications.
The CS16 column has the highest capacity among Dionex carboxylate-based cation columns, resulting in improved loadability and resolution. Use the CS16 with the Eluent Generator for simplified, consistent methanesulfonic acid eluent preparation. Use the Cation Self-Regenerating Suppressor (CSRS? 300) with standard or microbore CS16 columns or the Cation Capillary Electrolytic Suppressor (CCES? 300) with the CS16 capillary column.
