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.
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.
CAN114: Quantification of Trace and Major Anions in Water by Ion Chromatography in a High-Throughput LaboratoryInstrument Type: IC
Laboratories split their methods because good resolution for the major inorganic anion peaks and a low LOD for bromate determination is a difficult compromise to achieve. This application is a 2 channels method for the determination of fluoride, chloride, chlorite, chlorate, bromide, bromate, nitrite, nitrate, sulfate, and phosphate in different types of water samples without compromise between the sample volume injected in the chromatographic system and a low limit of quantification suitable for trace bromate determinations. 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.
TN23: Ion Chromatography of Lanthanide Metals (Part 2/3: Anion Exchange Separation of Lanthanide Metals)Instrument Type: IC
The separator column used for this method is the IonPac CS5.The separation is achieved using opposing linear gradients of a-hydroxyisobutyric acid (HIBA) oxalic acid and diglycolic acid.
