The water confines the sample to the proper locations within the apparatus, isolates the sample from the atmosphere, and enables the sample to be "pumped" by raising and lowering the water flask. You might be able to find further information by Googling "Orsat".

You're quite welcome. Much gas analysis these days is done by electronic meters, but some of the older folks still remember a bit about lab glassware techniques.

With gas analysis you can detect hydrocarbons, mercaptanes, SO2 and other poisonous products as part of the stream. The water brings these in solution, reducing the damage, they can produce. (some concentrations are in the ppm range to be deadly) In our laboratory we make our sample gas for gas chromatography ourselves to find retention times and the "peaks" in the samples. More info available if requested.
