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.

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.

AN1145: Determination of Halogens in Coal Using Combustion Ion Chromatography

Instrument Type: IC

When coal is burned, the exhaust contains halogens that can be released into the atmosphere as acid gases such as hydrogen chloride (HCl) and hydrogen fluoride (HF), which can harm vegetation, animals, and infrastructure directly or cause acid rain. In this application note, coal samples were combusted in the Mitsubishi AQF-2100H system and then fluorine and chlorine were accurately and precisely determined using the Dionex ICS-2100 Ion Chromatography System with a Dionex IonPac AS15 anion-exchange column set.

Determination of Chloride in Algal Oil Using Combustion Ion Chromatography

Instrument Type: IC

Oil extracted from fish and algae is a renewable alternative to petroleum-based sources. If this oil is used as a lubricant, chloride needs to be monitored and its level minimized to reduce the likelihood that corrosive HCl will form. By using a combustion ion chromatography (CIC) system consisting of the automatic quick furnace AQF-2100H and an ICS-2100 ion chromatograph, the concentration of chloride can be determined accurately and quickly.
