Summary
In order to carry out accurate analysis of the oxygen dissolved in mire waters a method was devised for withdrawing water samples, relatively free from particulate matter, without contamination by atmospheric oxygen. A probe is introduced into the substrate, a few minutes are allowed for the collection chamber to become filled with mire water, and the sample is pumped out into a collecting bottle for analysis. The depth of insertion of the probe may be altered, samples may therefore be collected from different rooting zones for chemical or dissolved gas analysis.
