AB137: Determination of Inorganic and Organic Acids in Apple and Orange Juice Samples Using Capillary ICInstrument Type: IC
Determinations of organic acids in fruit juices are used by the beverage industry for flavor characterization, identification of spoilage, identification of adulteration by a less costly juice, and product labeling. In this study, inorganic anions and organic acids in diluted filtered apple and orange juice samples were determined on a Dionex IonSwift MAX-100 anion-exchange column using electrolytically generated hydroxide gradient from 0.1–65 mM KOH over 25 min at 15 μL/min.
TN124: Determination of Inorganic Anions in Acid Rain Using a Dedicated High-Pressure Capillary Ion Chromatography SystemInstrument Type: IC
Ion chromatography is a well-established technique for determining inorganic anions in acid rain. This Technical Note describes the determination of inorganic anions in rain samples by employing high-pressure ion chromatography (HPIC) and the use of a 4 µm particle size column, the Dionex IonPac AS18-4µm.
AB136 (a): Determination of Inorganic Counterions in Pharmaceutical Drugs Using Capillary ICInstrument Type: IC
Approximately 50% of all drugs on the market are developed in salt forms. IC with suppressed conductivity detection plays an important role in the salt selection process to establish correct molecular mass of the entity in early stages of drug development. This study describes the determination of inorganic anions (a) and cations (b) in two different drugs using the capillary Thermo Scientific Dionex ICS-5000 system.
TN120: Fast Separations of Counter Ion in an Allergy Drug Tablet Using High-Pressure Capillary ICInstrument Type: IC
This application demonstrates the advantages of high pressure capillary IC using the high efficiency Dionex IonSwift MAX 200 capillary size anion-exchange monolith column to provide high sample throughput by simply increasing the flow rate on a high pressure capable Dionex ICS-5000+ HPIC capillary IC, resulting in saving time and money. An ICS-6000 can be used for this application.
AB140: Fast Determination of Inorganic Counterions in a Pharmaceutical Drug Using High-Pressure Capillary Ion ChromatographyInstrument Type: IC
This application brief describes the determination of counter anion chloride in a drug for type 2 diabetes using the Thermo Scientific Dionex ICS-5000 capillary IC system and Dionex IonSwift MAX-100 capillary column. The Eluent Generation Cartridge lasts 18 months under this condition in continuous operation mode and each analysis is less than 8 min.
