Oxygen Flask Combustion Unit

The Schöniger flask method is a well proven technique for the combustion and then subsequent analysis of a range of elements including Chlorine, Bromine, Iodine, Sulfur, Phosphorus and a number of metals. The combustion of the sample is a simple procedure and involves placing a few milliliters of absorbent solution in a flask. The sample is weighed out and placed in an ashless filter paper holder which in turn is placed in a platinum basket attached to the stopper of the flask. The flask is filled with oxygen and the stopper is then placed in the flask. The sample is combusted and the resultant combustion products are absorbed into the solution. The technique chosen for the actual determination of the element in question can be any one of a number of different techniques i.e. titration, ion chromatography, etc. The Schöniger flask combustion method is capable of being used for the determination of percentage levels to parts per million. It can cope with a wide range of sample types and is simple to set up with minimal start up costs.
