The M4 Knick CR cation resin columns are the ideal container for performing a cation exchange. Cationic resin columns remove cations in a sample through a dosing compound. This process is necessary to eliminate the masking effects of known chemicals such as ammonia or dissolved amines. In this exchange mechanism, the cations are exchanged for H⁺ ions, which pass from the active sites of the resin to the sample stream. The columns have a deep bed depth that ensures adequate residence time and as a result, process efficiency is increased. In addition, the columns have integrated retention filters on both the bottom and top of the device. These retain the resin in the column and allow the sample to pass without affecting the exchange process. Furthermore, M4 Knick’s resin columns have a fast response time of 4-5 minutes. To regenerate the resin, operators can simply wash the resin with HCl 5%. Lastly, resin columns are available as part of a sample conditioning panel or as a component for existing panels.
