Oxygen Flask Combustion Method

* (Excluding Mailing and Handling)

This method was invented by Wolfgang Schoniger in 1955 and it is useful

technique utilized for the estimation and identification of some combusting organic

compounds of sulfur or halogen in medicine. These compounds include chlorine,

bromine, fluorine, sulfur, etc. This technique was also named as Schoniger oxygenflask

technique, and it has been modified to tracing, and analyzing the compounds. The

compounds which are organic and some other polymers all these are experimented by

this technique in microgram amount.

A 500 ml conical flask of heavy wall was used in this method. The test solution was

prepared in two different ways for solid as well as liquid samples. For solid samples the

required quantity of selected sample in a specific amount at the center part of filter

paper were used. For liquid samples appropriate quantity of absorbent cotton along

with filter paper of size (50 mm-length/5 mm-width) was used. The procedure of the

determination of chlorine, and bromine, Iodine, Fluorine, and Sulfur were discussed.

The chlorine and bromine test was experimented with the help of blank solution in a

same quantity to make necessary correction. The Iodine test was experimented with the

help of blank solution in a same quantity to make necessary correction. Fluorine test

was performed with the required prepared solutions under ultraviolet visible

spectrophotometry. Lastly, the sulfur test was performed with required quantity of

blank solution in a same manner. This method covers the introduction part along with

method of sample preparation, and the important applications of oxygen flask method

were studied.
