Description
Cation multi-element standard (IC) is a ROTI®Star CRM 7 cations preparation with concentrations expressed in mg/l. The solution contains NH4⁺ at 1000 mg/l, Ca²⁺ at 1000 mg/l, K⁺ at 1000 mg/l, Li⁺ at 1000 mg/l, Mg²⁺ at 1000 mg/l, Na⁺ at 1000 mg/l and Mn²⁺ at 1000 mg/l in 0,1 % HNO3. Density (D) is approximately 1 g/cm³ and the boiling point (bp) is approximately 100 °C. The pack size is 100 ml and the pack weight is 0,123 kg. The standard is intended for ion chromatography (IC). All seven cations are present at the same 1000 mg/l concentration in the dilute nitric acid matrix. This cation multi-element standard from manufacturer Carl ROTH is sold as ROTI®Star CRM 7 cations. Laboratories receive a 100 ml unit of the seven-cation mix in 0,1 % HNO3, with the stated density and boiling point. The composition covers ammonium, calcium, potassium, lithium, magnesium, sodium and manganese as the listed cations. Use is as an IC multi-element cation standard at the concentrations given.
