Dionex IonPac CTC陽離子捕獲柱包含高容量，低效率，在氫離子型陽離子交換樹脂，從洗脫液去除微量陽離子污染物。
Thermo Scientific 戴安IonPac CTC-1和CTC 500陽離子捕獲柱包含高容量，低效率，在氫離子型陽離子交換樹脂，從洗脫液去除微量陽離子污染物。陷阱被安裝在現有的噴射閥，以防止假峰和梯度色譜過程中減少基線漂移洗脫液線。該戴安委員會的IonPac 500支持HPIC?系統壓力達5000磅（34.5兆帕）。對于RFIC?MSA淋洗液代應用程序，使用戴安CR-CTC。

The Thermo Scientific? Dionex? IonPac? CTC-1 and CTC 500 Cation Trap Columns contain high-capacity, low-efficiency, cation-exchange resin in the hydronium ion form, to remove trace cation contaminants from eluents. The trap is installed in the eluent line prior to the injection valve to prevent spurious peaks and reduce baseline shifts during gradient chromatography. The Dionex IonPac CTC 500 supports HPIC? system pressures up to 5000 psi (34.5 MPa). For RFIC? MSA eluent generation applications, use the Dionex CR-CTC.
