IonPac AS15毛細(xì)管柱(0.4x250mm)性能與標(biāo)準(zhǔn)孔柱相同，但只需 1% 的淋洗液流速，從而幫助降低運(yùn)行成本

IonPac AS15柱專為分析半導(dǎo)體和發(fā)電行業(yè)使用的高純度水基質(zhì)中的痕量陰離子的測(cè)定而設(shè)計(jì)，高容量和選擇性使高純水基質(zhì)中無機(jī)陰離子和低分子量有機(jī)酸的痕量濃度的測(cè)定獲得更好的效果。為實(shí)現(xiàn)性能，請(qǐng)使用 Thermo Scientific™ Dionex™IonPac™AC15濃縮柱進(jìn)行超痕量（萬億分之一）分析，使用 Dionex淋洗液發(fā)生器進(jìn)行簡(jiǎn)單的淋洗液制備，將 Thermo Scientific™ Dionex™陰離子自再生抑制器 (ASRS™300)或Thermo Scientific™ Dionex™ 陰離子毛細(xì)管電解抑制器 (ACES™300)與Dionex IonPac AS15 柱聯(lián)用，以實(shí)現(xiàn)淋洗液抑制。
