AN-CIC-003
Chlorine, bromine and sulfur in low-density polyethylene (ERM®-EC680k) using Combustion IC
The determination of halogens and sulfur in waste products is important. The inline combination of the Mitsubishi Combustion Module with the Metrohm IC is a suitable method for this type of samples. The recovery rates are analyzed with a certified reference material, e.g., a low-density polyethylene (LDPE).Keyword: pyrohydrolysis
AN-CIC-004
Total and leachable concentration of halogens and sulfur in latex gloves using Combustion Ion Chromatography and a leaching test
Latex gloves are used in clean room environments in order to prevent contaminations. The use of gloves that release corrosive halogenides or sulfate is forbidden in nuclear power plants. The total content of halogen and sulfur is determined by means of Combustion Ion Chromatography. An eluate test is carried out to check the elutable percentage of halogens and sulfate from gloves. Sample preparation is comprised of preconcentration and matrix elimination (MiPCT-ME), as described in AN-S-304.Keyword: pyrohydrolysis
AN-CIC-005
Iodine in a pharmaceutical product using Combustion Ion Chromatography with Inline Matrix Elimination
The iodine content in numerous iodized X-ray contrast media (ICM) is around 50% and is determined with great accuracy using Combustion Ion Chromatography. Large quantities of H2O2 (1,000 mg/L) are required for complete absorption of the iodine. Similarly, the concentration of the internal standard should be 50 mg/L. The water content of the X-ray contrast media is determined by means of Metrohm's Karl Fischer oven method and incorporated in the final calculation.Keyword: pyrohydrolysis
AN-CIC-006
Recovery rates of chloride, bromide and sulfate in certified reference materials using Metrohm Combustion Ion Chromatography
Combustion Ion Chromatography combines pro-hydrolytic sample combustion and the absorption of emerging combustion gases in an oxidizing, aqueous solution that is then channeled to an ion chromatograph for the analysis of halogenides and sulfur (as sulfate). The combustion and analysis of the certified reference materials (ZRM) makes clear the reliability of Metrohm Combustion Ion Chromatography.Keyword: pyrohydrolysis
AN-CIC-007
Analysis of a standard mixed in liquid using Metrohm Combustion IC

Halogens in a polymer sample applying Metrohm Combustion IC according to IEC 60754
The Restriction of Hazardous Substances Directive (RoHS) requires to reduce the halogen content in several organic materials used in electrical and electronic equipment. In this context, there is a huge interest for using halogen-free polymers. To check for halogens in polymers according to standard IEC 60754, Metrohm Combustion IC applying flame sensor technology and Inline Matrix Elimination is an indispensable method. The examined polymeric material contains halogens at a level of up to 1%.
AN-CIC-011
Analysis of an ion exchanger using Metrohm Combustion IC
The manufacture of ultrapure water for the pharmaceuticals industry or the semiconductor industry requires high-quality ion exchangers. Metrohm Combustion Ion Chromatography is an indispensable tool in this connection for testing the purity of anion exchange material. The output sample was wet and had to be dried at 105 °C in a special oven with waste air evacuation.Keyword: pyrohydrolysis
AN-CIC-012
Halogens and sulfur in clay using Metrohm Combustion IC
Clay is used for the manufacture of roofing tiles. Quality controls during this process require the determination of halogen and sulfur content. This is ideally accomplished using Metrohm Combustion IC. With this method, the sulfur is determined as sulfate and the halogens as halogenides. Because clay often contains high contents of alkali and earth alkali metal ions that attack the pyrolysis tube, tungsten oxide is added prior to combustion.Keyword: pyrohydrolysis
