Abstract
The invention relates to a material for the quantitative removal of water from a gas stream containing molecular sulphur and/or sulphur-containing compounds, in particular a gas stream supplied for gas analysis. This material contains at least 60% by weight of a granular carrier material which is inert to sulphur compounds, in particular sulphur dioxide, and between 5 and 35% by weight of magnesium perchlorate. The invention also comprises a device for purifying gas streams which is used with the material according to the invention and the use of the material in gas analysis.
Claims12
Material for the quantitative removal of water from a gas stream containing molecular sulphur and/or sulphur-containing compounds, characterised in that the material contains at least 60% by weight of a carrier material designed as granules, which behaves inertly towards sulphur and sulphur-containing compounds, and between 5 and 35% by weight of magnesium perchlorate, characterised in that the material additionally contains calcium chloride and the proportion of calcium chloride is between 5 and 35% by weight.
Use of a material for the quantitative removal of water from a gas stream containing molecular sulphur and/or sulphur-containing compounds in a gas analysis system (20) for the determination of nitrogen, carbon, hydrogen and/or oxygen, wherein the material contains at least 60% by weight of a carrier material designed as granules, which behaves inertly towards sulphur and sulphur-containing compounds, and between 5 and 35% by weight of magnesium perchlorate.
Use of a material for the quantitative removal of water from a gas stream containing molecular sulphur and/or sulphur-containing compounds in a TOC analysis or an IRMS analysis, wherein the material contains at least 60% by weight of a granular carrier material which is inert to sulphur and sulphur-containing compounds, and between 5 and 35% by weight of magnesium perchlorate.
