OmniPac Columns 當(dāng)反相色譜和離子交換色譜柱都不能分離被分析樣品時,，建議試試該OmniPac® 色譜柱，或者Acclaim混合基質(zhì)色譜柱,。色譜柱結(jié)合離子交換和反相性能后,，能產(chǎn)生多重的分離能力與被分析物作用分析樣品,。該色譜柱固定相為聚合物填料，適用于同時分離陰離子和陽離子模式,。Acclaim 混合基質(zhì)柱是硅膠基質(zhì)柱,，適用于同時分析陰離子和親水性液相色譜分離（HILIC）模式。
DVB polymer columns for combined ion-exchange and reversed-phase separations The OmniPac PAX-100 column is used to separate hydrophobic anionic analytes such as larger organic acids. The OmniPac PAX-500 simultaneously separates anionic and neutral species.The OmniPac PCX-100 separates low-molecular-weight hydrophobic cations. The OmniPac PCX-500 simultaneously separates cationic and neutral species in a single run.
• Acid-, base-, and solvent-compatible, pH 0–14
• Ideal for the separation of high-molecular-weight organic acids• Delivers optimal separation of very hydrophobic anions
• Delivers optimal separation of halogenated anions
• Delivers simultaneous separation of neutral and ionic species
• Unique selectivity for polar and ionic organic analytes
• Delivers optimal separation of organic, hydrophobic, and halogenated cations
The OmniPac PAX- and PCX-100 and 500 are latex-based columns. Both PAX columns have an ion-exchange capacity of about 40 μeq per column, providing equivalent anion-exchange separations. The PCX columns have a capacity of approximay 120 μeq per column. The PAX- and PCX-500 columns separate analytes through both ion-exchange and reversed-phase mechanisms, due to their higher reversed-phase capacity relative to the PAX- and PCX-100.
The OmniPac PAX-100 column was one of the first 100% solvent-compatible, anion-exchange columns developed for the separation of inorganic and organic anions, providing acid and base compatibility over the entire pH range. Because the OmniPac PAX-100 is solvent compatible, solvents can be used to modify the ion-exchange selectivity.訂貨信息：
