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

• 專為測定多種樣品基質(zhì)中差異極大的鄰近洗脫陽離子（如鈉離子和銨離子）濃度比例而優(yōu)化。

• 在存在鋰、鈉、銨、鉀、鎂和鈣的情況下，測定復(fù)雜樣品基質(zhì)中的短鏈烷基胺和烷醇胺。

• 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。

Dionex IonPac CS16 陽離子交換柱

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.
