Ammonium – Sequential suppression with linear calibration

IC Application Note CS–003 Biogenic amines besides standard cations with suppressed conductivity detection applying a Dose-in Gradient Biogenic amines are quality markers for food samples as e.g., fish and wine. Here, the simultaneous separation of standard cations, putrescine, cadaverine, and…

IC Application Note CS–010 Traces of lithium and sodium besides monoethanolamine in water-steam circuits of thermal power plants Boiler feed water is the operating medium in thermal power plants. To suppress corrosion, the pH value of the feed water is…

IC Application Note CS–011 Trace cations in lithium hexafluorophosphate Lithium hexafluorophosphate (LiPF6) is used as electrolyte in rechargeable batteries. Particularly the high solubility in non-polar solvents and the non-coordinating character of the hexafluorophosphate anion make it ideally suited for lithium-ion…

IC Application Note CS–009 Suppressed cation chromatography improves the detection limits for cations. To obtain these lower limits, the blank cation concentrations from sample vials gain high importance. The leaching test of several types of vials is performed by intelligent…
