AU204: Determination of Inorganic Cations and Ammonium in Environmental Waters Using a Compact Ion Chromatography SystemInstrument Type: IC
This Application Update revises AN141 using the compact, integrated Dionex Integrion HPIC system with a Dionex IonPac CS16-4μm cation-exchange column. Inorganic cations and ammonium in environmental waters are determined using a 4 μm particle 4 mm i.d. cation-exchange column to shorten analysis time.
Determination of Inorganic Cations and Ammonium in Environmental Waters by Ion Chromatography Using the Dionex IonPac CS16 Column with a Compact Ion Chromatography SystemInstrument Type: IC
This record describes the use of IC with a 5 mm i.d. Dionex IonPac CS16 cation-exchange column, an electrolytically generated methanesulfonic acid (MSA) eluent, and suppressed conductivity detection to determine dissolved alkali and alkaline earth cations and ammonium in municipal wastewater as published in Application Note 141. In this record the method was executed on an Integrion ion chromatography system.
IC Assay for Lithium, Sodium, and Calcium in Lithium Carbonate Using a Compact Ion Chromatography SystemInstrument Type: IC
Lithium carbonate is used to treat a number of mental health problems associated with chemical imbalance in the brain. Sodium and calcium are possible cationic impurities in lithium carbonate preparations. This record shows a method that uses a Thermo Scientific Dionex IonPac CS16 cation-exchange column, an electrolytically generated MSA eluent, and suppressed conductivity detection to determine lithium, sodium, and calcium in lithium carbonate that was published in Application Note 1090. In this record the method is executed using an Integrion ion chromatography system.
Determination of Ammonia in Sodium Bicarbonate Using a Compact Ion Chromatography SystemInstrument Type: IC
One of the main pharmaceutical uses of sodium bicarbonate is for hemodialysis. For hemodialysis-grade sodium bicarbonate, the quality and purity requirements are stringent. Ammonia is one of the impurities that is assayed in sodium bicarbonate because the presence of elevated levels of ammonia in the blood stream can have adverse effects. This record describes an ion chromatography (IC)-based method for the determination of ammonia (as ammonium) in sodium bicarbonate that was published in Application Note 1073. In this record the method was executed using an Integrion IC system.
AB133: Cost-Effective Determination of Inorganic Anions and Cations in Municipal Drinking Water Using Capillary Ion Chromatography (Cations)Instrument Type: IC
This study describes the determination of inorganic anions and cations in drinking water using the Thermo Scientific Dionex ICS-5000 capillary IC system. Here shows the determination of inorganic cations in drinking water using Dionex IonPac CS12A capillary column.
