Summary
A novel G.C. method has been devised for the determination of dissolved oxygen in soil water. To eliminate the interference in the determination caused by water, a pre-cut column is used. The water trapped by the pre-cut column is removed by the streaming of a carrier gas in the reverse direction after the G.C. recording of oxygen, by which repeated measurements are greatly facilitated. The volume of the sample solution required for each run is 10μl. re]19751110
