No suppression – Simultaneous determination of monovalent inorganic ions using HPLC-ELSD

Application No.: VCH0019

No suppression – Simultaneous determination of monovalent inorganic ions using HPLC-ELSD

 

Commonly the analysis of highly polar compounds is realized with ion exchange (IEX) or ion chromatography (IC) and so users are often limited to particular methods(1). These methods usually go along with the use of suppressors or other additional equipment to enable the detection by conductivity measurement. Using a special HILIC mixed-mode column in combination with evaporative light scattering detection (ELSD) allows to apply a simple isocratic method with a standard LC system configuration.
