AN72333: Determination of Adsorbable Organic Halogen in Wastewater using a Combustion Ion Chromatography System

Instrument Type: IC

This application note demonstrates that AOX can be precisely and accurately determined in wastewater using combustion ion chromatography. Analysis was automated using the Mitsubishi AQF–2100H system in combination with the Dionex Integrion HPIC system with a Dionex IonPac AS18-4μm column.

AN72268: Determination of Fluoride in Tea using a Combustion Ion Chromatography System

Instrument Type: IC

This application note demonstrates a simple combustion ion chromatography (CIC) method to determine fluoride in tea. Using the CIC system including a Mitsubishi Automatic Combustion Unit AQF-2100H system and a Thermo Scientific Dionex Integrion HPIC system, fluoride in tea is determined in 20 min (11 min if the combustion and chromatography functions are overlapped), a significant time savings over the current Chinese national method which requires more than a hour. The CIC method is sensitive (MDL=1 ppm), precise, and accurate. The only sample preparation required is to grind and dry the tea.

Dionex IonPac AS18-4μm Column Performance Test Using its QAR Method

Instrument Type: IC

Before running any samples, Thermo Scientific recommends that you first confirm the performance of the column by reproducing the lot validation report chromatogram shipped with column. Compare your results with the one reported in the quality assurance report. This record provides an eWorkflow for executing the QAR method on an Integrion HPIC system.

TN124: Determination of Inorganic Anions in Acid Rain Using a Dedicated High-Pressure Capillary Ion Chromatography System

Instrument 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.

AN1120: Determination of Anions in Process Water from Steam Assisted Gravity Drainage Oil Sands Extraction

Instrument Type: IC

SAGD is used for the extraction of hydrocarbons from oil sands. Recovered process water is treated to reduce ion content prior to reuse in steam generation. In this Application Note, water samples obtained from SAGD oil sands processing were analyzed using a Thermo Scientific Dionex ICS-5000+ Reagent-Free High-Pressure Ion Chromatography (HPIC) system for anion determinations using Thermo Scientific Dionex IonPac AS18-4µm capillary column. An ICS-6000 can be used for this application.
