Cation Multi-Element Standard (IC) is a ROTI®Star aqueous reference solution containing five cations at defined concentrations for ion chromatography: NH4⁺ at 100 mg/l, Ca²⁺ at 200 mg/l, K⁺ at 100 mg/l, Mg²⁺ at 100 mg/l and Na⁺ at 400 mg/l. Prepared in water, the standard supports calibration and system suitability checks in environmental analysis and routine IC workflows where simultaneous cation quantification is required. Physical data include a density of about 1 g/cm³ and a boiling point of 100 °C. Supplied as a 100 ml unit, this multi-cation preparation from manufacturer Carl ROTH is intended for laboratories that need a ready multi-component cation mix rather than individual single-element standards. It is well suited to water and environmental sample sequences, helping analysts establish linear response across ammonium, alkaline-earth and alkali cations in a single calibration set. The clear aqueous matrix simplifies dilution into working ranges typical of modern ion-chromatography methods.
