OmniPac Columns
当反相色谱和离子交换色谱柱都不能分离被分析样品时，建议试试该OmniPac® 色谱柱，或者Acclaim混合基质色谱柱。色谱柱结合离子交换和反相性能后，能产生多重的分离能力与被分析物作用分析样品。该色谱柱固定相为聚合物填料，适用于同时分离阴离子和阳离子模式。Acclaim 混合基质柱是硅胶基质柱，适用于同时分析阴离子和亲水性液相色谱分离（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 approximately 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. 订货信息： Analytical Columns OmniPac PAX-100 Analytical Column （4 × 250 mm）.................................... 042150 OmniPac PAX-500 Analytical Column （4 × 250 mm）.................................... 042152 OmniPac PCX-100 Analytical Column （4 × 250 mm）.................................... 042189 OmniPac PCX-500 Analytical Column （4 × 250 mm）.................................... 042191 Guard Columns OmniPac PAX-100 Guard Column （4 × 50 mm）.......................................... 042151 OmniPac PAX-500 Guard Column （4 × 50 mm）.......................................... 042153 OmniPac PCX-100 Guard Column （4 × 50 mm）.......................................... 042193 OmniPac PCX-500 Guard Column （4 × 50 mm）.......................................... 042195 应用谱图：
