Halogens in LPG applying Metrohm Combustion IC

The IC Application Note CIC–18 presents the determination of the halogens in a liquefied gas sample. Download the application note to learn more.

Combustion Ion Chromatography (CIC) extends the range of ion chromatography to all types of combustible samples. The focus here is primarily on the simultaneous determination of the various halogens and sulfur in widely differing matrices.

This IC Application Note CIC–18 addresses the determination of the fluorine and chlorine content of a liquefied gas sample (LPG, Liquid Petroleum Gas), i.e., halogens in a mixture of propane and butane. Fluorine originates from perfluorobutane and chlorine from methyl chloride. LPG/GSS modules are used to introduce 50 µL of sample into the combustion system. The halogens released during combustion are determined using ion chromatography with intelligent Partial Loop injection Technique following Inline Matrix Elimination.

The 930 Metrohm Combustion IC enables the analysis of halogens and sulfur in flammable samples of all types using inline combustion digestion with subsequent ion chromatography determination (Combustion IC). It comprises all required components, e.g., the Combustion Module from Analytik Jena (2.136.0700), the 920 Absorber Module, the 930 Compact IC Flex Oven/SeS/PP/Deg and the MagIC Net software. If necessary, the 930 Metrohm Combustion IC package can be supplemented with an Autosampler for solid or liquid samples (MMS 5000 Autosampler). The entire analysis, including sample input and sample digestion, is completely automated and is completely controlled by MagIC Net.
