SMT SAM IC – ionRes Ion Chromatography Column

Anion and Cation Ion Chromatography columns for IC separations. These columns provide high resolution and high efficiency.

Part Number:  N/A Category: Tag:


SMT uses a unique bonding scheme to manufacture very high ligand density silica-based Anion IC columns for separation of oxyhalides and general inorganic ions. SMT’s ionRes-A50 Anion IC Column packings consist of chemically attached hydrophilic surface derivatized to form quaternary ammonium via Total Coverage technology. The proprietary technology utilizes advanced Self-Assembled Monolayers (SAM) in the bonding process to significantly increase the functional ligand density. In addition, this procedure ensures highly cross-linked polysiloxane under layer structure. The results are bonded phases that are well protected and that show unprecedented resistance to both acid and base hydrolysis. Overall, SMT ionRes-A50 Anion IC Columns offer superior selectivity and efficiency.

Features of SMT ionRes columns include:

  • Provides superior analysis of general inorganic ions
  • Functional group – Quaternary ammonium for A50 and sulfonic acid for C50
