Which material is better for the column, SUS or PEEK?

Most of the liquids used in ion chromatography are aqueous solutions, so we recommend PEEK resin columns, which are easy to handle, for columns that are frequently installed and removed. By the way, PEEK resin is inert to compounds adsorbed to metals (ATP, ADP, etc.), so it improves problems such as non-eluting of components and tailing of measurement peaks.

If you are concerned about cost, a stainless steel (SUS) column would be a good choice. Some people shy away from using metal for piping because they are analyzing ions, but the stainless steel used for columns has excellent corrosion resistance, so there is no problem using it for ion chromatography.
