  • Errors in Sampling Procedure for the Determination of Dissolved Oxygen by Winkler Method

この論文をさがす

説明

Sources of systematic error in the sampling procedure by Winkler method were examined. In the laboratory experiment, the dissolution of atmospheric oxygen into oxygenfree sea water during sampling amounts to 0.022ml/l, and the effect of dissolved oxygen in sea water remaining in oxygen bottle is 0.019ml/l. The effect of reagents added amounts to 0.017ml/l. In the sampling procedures aboard, the effect of dissolution became bigger, and the table is presented for the correction to the reported value of dissolved oxygen measured by the “Manual of Oceanographic Observation”. The corrected value of dissolved oxygen in the routine analysis may not be correct within 0.02 ml/l.
