AU168: Determination of Transition Metals in Complex MatricesInstrument Type: IC
Chelation ion chromatography facilitates the determination of low concentrations (μg/L and lower) of transition metals in samples including seawater, brines, estuarine waters, and a variety of biological samples. Here, the authors simplify the system configuration described in Technical Note 25, using an ICS-3000 system. The separation has also been updated to include the IonPac CS5A/CG5A column set, which demonstrates improved selectivity and peak efficiency for separation of transition metals compared to the CS5.
AU158: Determination of Manganese in BrineInstrument Type: IC
Sodium chloride brines are used in chlor-alkali cells and must have low concentrations of alkali and alkaline earth metals to prevent membrane poisoning. When brines are prepared from seawater, the manganese concentration is also a concern. This application update uses the same separation conditions as AN 120, but alters the online sample preparation with the MetPac column to effectively concentrate manganese from 10 times more sample than used in AN 120.
AN108:Determination of Transition Metals in Serum and Whole Blood by Ion ChromatographyInstrument Type: IC
The determination of transition metals in physiological fluids is of considerable interest in clinical chemistry. This application note describes an attractive alternative to traditional spectroscopic methods by using the principles of ion exchange. Separation between individual metals can be enhanced or altered simply by changing eluents (pyridine-2, 6-dicarboxylic acid or oxalic acid). This figure illustrates the selectivity on an IonPac CS5A column when using a pyridine-2, 6-dicarboxylic acid eluent.
AN1053: Determination of Dissolved Manganese in Lithium/Manganese Oxide Battery ElectrolyteInstrument Type: IC
The application uses an RFIC system with suppressed conductivity detection to quantify dissolved manganese in the simulated electrolyte of a Li/LiMn2O4 battery. The method uses the Dionex IonPac CS12A column, which was designed to deliver good peak shapes for cations such as manganese(II) (Mn2+), with methanesulfonic acid (MSA) produced by an eluent generator. The method is sensitive, accurate, reproducible, and easy to execute, requiring only the addition of deionized water to the RFIC system.
