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.

AN72349: Determination of Chlorine, Bromine, and Sulfur in Polyethylene Materials using Combustion Ion Chromatography

Instrument Type: IC

Plastic samples can be very difficult to analyze as sample preparation is required to extract analytes or remove interfering matrices, and these sample preparation techniques can be labor intensive. In this application note, we demonstrate that a CIC system can be used for automated qualitative and quantitative analysis of halogens and sulfur in plastic samples. Four plastic samples were analyzed for their chlorine (Cl), bromine (Br), and sulfur (S) content. Method accuracy was evaluated using a polymer certified reference material (ERM EC680k) for Cl,Br, and S.

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.

Determination of Chloride and Sulfate in Crude Oil by Combustion Ion Chromatography

Instrument Type: IC

In this application, crude oil was combusted in the Mitsubishi AQF-2100H system and then analyzed using a Dionex Integrion Ion Chromatography system to determine chloride and sulfate with a Dionex IonPac AS28-4µm anion exchange column.

Determination of Halogens and Sulfate in Liquid Petroleum Gas Using Combustion Ion Chromatography

Instrument Type: IC

In this application, Liquid Petroleum Gas (LPG) samples were combusted in the Mitsubishi AQF-2100H system and then fluoride, chloride, and sulfate were determined using the Dionex ICS-2100 Ion Chromatography system with a Dionex IonPac AS15 anion-exchange column set.
