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。

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.
